The Bold text in the exchange between Lily and Rhianon is Sindarin one of the Elvish Languages!
The year is 2024, in the mortal world.
On Ynys Afallach time passes so much slowing then the mortal realm One month in the real world is equivalent to one week. The Lady Of The Lake received an owl from her old friend and mentor Minerva McGonagall. Reading the message label, it reads
Lady of The Lake
We have a first year, that we want you to evaluate!
"She has the ability of a 7th Year"
Minerva McGonagall
Headmistress
Hogwarts School of Witchcraft and Wizardry
This Sounds Promising! The Women with waist long red hair thought, James must go for sorting anyway!
"I really must show Minerva
"Harry" Ginevra called into thin air only to hear Harry respond "HHHMM!"
"It appears when we take James & Lilly to Hogwarts, we may be bring a transfer student back with us!"
Looking up from whatever he was doing Harry's brow shot up to a high speculative arch, as his wife Ginevra said, "Apparently they have a first year with the ability of a 7th!"
That got Harries Attention real fast asking, "Did the Headmistress include family background!"
"No… and I got the distinct impression she didn't want to discuss it via owls so" Ginny said re reading the scroll.
"Still" Harry said, "To have that level of Talent and no formal training it would have to be an old Bloodline!"
"Gagh!" Lilly mutters storming into the room asking, "Mom do I have to go back to Hogwarts I already know more than most of the teachers… I don't even need a wand to cast!"
Stopping mid-sentence Lilly said, "You may want to send the barge Aunt Hermione's coming!
Meanwhile on the shore Hermione Granger-Weasley waited as the barge to Ynys Afallach came into sight at the prow of the barge itself was The Lady of Afallach herself.
"Welcome Abord" Ginny called, as one of the boatmen helped her aboard.
Looking at her sister-in-law Ginny said, "Hermione, you will see Elves on Ynys Afallach do not start a branch here!"
The look on Hermione's face said, "But they!"
Pouring some tea Ginny said, "They are not the Elves your used to, for starters they are 6 feet tall and they are not considered adults until the age of 750."
Here we have Wild Elves and Wood Elves, Handing her a cup Ginny said, "Hermione some of the Elves here are well over 1,350 years old, they will take your actions as a declaration of war"
When they arrive, they see Lilly speaking to a female Wild Elf in a language Hermione can't understand!"
Ginny Laughs saying, "It's Old Cyrodiil Lilly started learning it at age 5, Wild Elves rarely if ever share knowledge with outsiders, that is a tribe Shaman!"
Looking up Lilly said, "Things that Neville Longbottom doesn't know!"
Looking at Hermione The Wild Elf said, "I speak your tongue young one!" in perfect English.
Reading the question on Hermione's face The Shaman said, "I found her walking in the woods one day, and she looked right at me!"
It was Ginny that spoke up saying, "You can't spot Wild Elves in the forests unless they want to be seen!"
"Hermione Granger-Weasley" The Elf said, "My kin in your Forbidden Forest told me how you tried to free Elves, you almost undid a peace that was made ages ago!"
The Shaman's aged eyes bore into her as Hermione flinched, The Shaman spat, "Who do you think taught the first Witch and the first Wizard… Elves"
In your way of measuring time it was (2600 BC!) There was a feud between Cliodna and The High Elves what you must understand is High Elves were the first of our kind. it was a High Elf that taught Cliodna magic."
"Why isn't this in any magical history books?" Hermione asks as her speculative voice rose half an octave realizing. The were the royaly family… of Elven kind
The Shaman looked at Hermione saying in a cold matter of fact tone, "Because we came close to wiping the human Magi out of existence!"
"As was the custom at the time hostages were exchanged so no attacks happened!" With a light chuckle at the memory The Shaman said, "Cliodna thought Elven Law was negotiable we have only 5 laws and in all the ageless Millenia none of our kind has violated them explaining"
We Elves expect guests to know and abide by our laws (as does any culture). Elven laws are simple Hermione:
1. Theft is forbidden
2. Murder is forbidden
3. No treasonous acts under any condition
4. Warriors shall obey the Laws of Honor in warfare (only enforced in Elven war)
5. One does not harm or threaten a bard
Only then did Hermione put the pieces together as she thought, The hostages became the first house elves, in an act of vengeance!
"If you are a Magi, or Wizard in our culture your apprentice must be approved of by the one that taught you." The Shaman explained, "Cliodna never sought that approval and in doing so betrayed the one she was apprenticed too!"
"Forgive me!" Tentatively she looked at The Shaman and Hermione said, "You speak if these events as if you were there!"
"I was!" The Shaman said, "As to why this is not in a scroll or a book, Nothing sacred is written down"
"Hermione!" Smiling The Shaman said, "You may call me Shanyrria!"
"I mean no disrespect!" Hermione states, "Why"
"Because young one, you've asked a right question!" Shanyrria said looking at Ginny saying, "You may show her one of the old paths!"
One of the old Paths… Hermione thought.
Reading Hermione's thoughts Shanyrria said, "Only you may come!"
Shanyrria sees images of Hermione's, daughter Rose and says, "She would have done well here!"
Hermione spun on a dine asking, "Who would have done well here!"
"Your daughter Rose!" Shanyrria said, "She is the only other that may come here No Men Allowed!"
A few hours later at The Great Lake within the grounds of Hogwarts a Mist starts forming making the opposite shore impossible to see, all anyone could hear was something breaking the water every few moments.
A barge with a 5′ 6″ women with hair down to just below the waist in a bluish violet dress and a 5'3" women with tanned skin and a tattooed face dressed in leathers accompanied by a man dressed in a whitish robe with a blue hue walk onto the grounds of Hogwarts from the lake.
Off to the side Harry sees someone trying to make it rain and doing a competent job of it much to the chagrin of his victim.
Giving the girl a wink Harry starts whistling in an extremely specific tone and the longer her whistles the faster the rain clears!
"HOW DARE YOU RUIN MY FUN" The 6th year screamed
"Looking at the boy, Harry's eyes had an intensity that said, "Don't" as he said, "SILECNCE!"
In a low menacing voice, Harry said, "Now that I have your attention, count yourself lucky that you go to Hogwarts and are not my apprentice"
"You may speak!"
The boy's breathy rasp tried to form words as his larynx relaxed after Harry made it rapidly constrict, with nothing more than a thought.
The boy watched as lighting begin forming in Harry's eyes. Not understanding the warning Harry gave him, he began to retaliate for his dressing down when clouds start gathering overhead and the sky started to darken, and everyone heard, rrrrrrrrrrrrrrrrrRRRRRRRRRRRRRRRR, -(Crack)-RRRRRRRRRRRRRRRRrrrrrrrrrrrrrrrrrr.
In the blink of an eye Lighting strikes the ground between the 6th years feet, and Harry said, "You dabble in elemental magic" His stern gaze bore down on the student as he said, "Children should not play with things they little understand!"
The first-year girl looked at Harry thinking, Did he just whistle down the wind… and create a lightning strike… the only one that could do those things was the founder of my line!
Harry kept walking away from the boy one of the Wild Elves from the Forbidden Forest walked up to him and said, "Master Myrddin what brings you here!"
The boy's face went blanch white when he heard the name deciding not to pursue his vengeance!
The first year heard the name the Wild Elf used and thought, Myrddin!...
Headmistress Minerva McGonagall arrived on the scene moments later, in her mind Minerva heard harry say, Call me Myrddin… I don't want him to know who I am… for the moment!
As the clouds dissipate and the sun returns, she gives him a wink and a nod as Minerva said, "That was quite the display Master Myrddin!"
Quite the display indeed! Minerva McGonagall thought to herself, leaning in Harry said, "As much as I hate displays like that sometimes they are the only way"
As an afterthought and with a light chuckle he said, "I find It focuses a person's attention quickly!"
"Your friend!" Minerva McGonagall asks inclining her head.
"My daughter Lilly's Tutor apparently there are those who question how and why!" Myrddin said, "She is a Wild Elf of Ynys Afallach and a Shaman!"
"I see!" Minerva said, raising an Eyebrow at the women.
"I speak your tongue… Headmistress, my name is Shanyrria!" The tattooed women said, "Apparently your instructors have a problem with my apprentice not needing a wand to cast spells, and not needing to speak!"
"Lillui tul- hi a moment!" Shanyrria called as Lilly Potter walked over saying, "Yes Shanyrria cin wanted na see nin?"
Switching to English Shanyrria said, "Call down the wind for me!"
Like her Father had done only moments ago Lily started whistling in an extremely specific tone and the wind starts to pick up, Lily said, "The secret is in the tone!"
"Shanyrria doesn't believe in using Spells or incantations!" Lily said as if it were nothing!
"Yes… be that as it may!" Minerva said producing Lily notes from last term asking, "and this!", holding out the notes to her.
"That's Tengwar" Lily said, "The Written Form of The Elivish language!"
Minerva raised speculative a brow as Lily said, "I was tired of people taking my notes… without asking!
"You mean they would Cheat!" Headmistress McGonagall asked, only to have Lily nod in confirmation as she said, "If they can't read them!"
One hour later Shanyrria was strolling the school greenhouses and shaking her head, when Professor Neville Longbottom asks, "May I help you!"
In an Aged singsong voice Shanyrria said, "I think you have that backwards child… Those Plant's need to be with the great mother not separated in pots!"
Shaking her head Shanyrria said, "When you think of Elves you think of your kitchens staff, you're not used to seeing elves like me!"
That evening at dinner everyone noticed 3 extra seats at the teachers table Stepping up to the Dias Headmistress McGonagall said, "No doubt your wondering why there are 3 extra seats at the Table, no we are not getting new professors!"
to her right Headmistress McGonagall said, "Please welcome The Lady of Ynys Afallach, and Shaman of the Wild Elves of Ynys Afallach Shanyrria"
Standing Shanyrria said "Lothron i blessings -o Ynys Afallach n- upon cin all!"
In that same moment Lily stood and translated the statement saying, "May the blessings of Ynys Afallach be upon you all"
After the room settled down the one thing the people closest to the table noticed about Shanyrria is how striking her facial tattoos were.
Gesturing with her other hand Headmistress McGonagall said, "This is Myrddin… also of Ynys Afallach"
Later that night in Headmistress McGonagall's office Minerva was about to light the fire when Ginny glanced at the fireplace and flames burst forth.
As both Harry and Ginny took their seats the girl that Harry rescued that morning walks in and blinks saying, "You, you stopped him!"
"Yes… I did!" Harry said softly, the Girl still had not made the connection as Harry's beard helped hide who he truly was.
"You're a Gryffindor then!", Giving the girl a wink Harry said, "So was I!"
The girl looked at him not quite sure what to believe asking, "You were!"
The women known only as The Lady of Ynys Afallach said, "We both were!"
"My name is Rhianon, the founder of my line is Gwion Bach ap Gwreang!"
At that both Ginny and Harry gave each other a sideways glance that Headmistress McGonagall couldn't miss, asking, "Does that name mean something to you!"
"Indeed, it does Headmistress, Gwion Bach ap Gwreang or Gwion Bach is the birth name of the Bard Taliesin, he was also the first Myrddin!"
"Rhianon!" The Lady of Ynys Afallach said, "You may come with us when you return to Ynys Afallach!"
Swallowing hard Rhianon said, "I'm going to become… I priestess!"
Lily… The Lady of Ynys Afallach thought, Come to Headmistress McGonagall's office!
15 minutes later Lily Luna Potter walked in the office and greeted The Lady of Ynys Afallach saying, "Mom you need me for something!"
Only then did Rhianon start putting the pieces together thinking, Lily Luna Potter just called The Lady of Ynys Afallach mom, that means her father is!
If cin oiale baur nin dilthen sister ped- nin est- a im shale hen, Lily said spotting the pointed Elvish ears.
"Rhianon only my friends call me Harry!"
Rhianon turned to Lily and said, "You speak… Sindarin!" Cin ped-… Sindarin!"
"Fluentlui, a im tur- read a teith- Tengwar!" "Fluently, and I can read and write Tengwar!" Lily said softly,
"Excuse me Headmistress, you may want to let Shanyrria in!" Looking at Headmistress McGonagall Lily said, "She is Very, in her mind your braking Elven law, the 5th law to be exact… One does not harm or threaten a bard!"
Before Headmistress McGonagall can answer Ginny said, "Elves are very literal in their mindset, by locking that door to her you are!"
Walking over to the Aged Wild Elf and in a soft soothing voice Lily said, "Shanyrria im am unharmed Headmistress McGonagall was ú- trying na cheb- nin o cin. Tul- ennas na- someone cin should govannon-."
Shanyrria I am unharmed Headmistress McGonagall was not trying to keep me from you... Come there is someone you should meet...
Lily led Shanyrria over to where Rhianon stood and Lily said, "Rhianon hi na- Shanyrria -o Ynys Afallach!" "Rhianon this is Shanyrria of Ynys Afallach!"
Taking it Rhianon, Shanyrria said, "Cin are Quendi!" "You are Quendi!"
Turning just a hint of crimson Rhianon said, "Nin tí starts with Quendi a i Bard Taliesin! "My line starts with Quendi and The Bard Taliesin!"
Switching back to English Shanyrria said, "Rhianon you could live to be well over 200 or possibly 2000 depending on the Quendi bloodline!"
Every head in the room snapped to Shanyrria, as she said, I would need to test you to be sure!"
"Forgive me!" Shanyrria said, "I wasn't considered an Adult until the age of 100 most Elves live past 6000 of your years"
"We stop aging at 50 to 100 Years!"
Ginny, Harry and Lily knew what statement was coming next as Shanyrria stated, "I don't measure time the same way Human's do, but I am 28,000 of your years!"
Headmistress McGonagall looked at Shanyrria thinking, 28,000!
Minerva Suddenly lost her balance muttering, "Of all the times to suffer residual effects!"
Looking at the women Shanyrria asks, "Crippling or Stunning"
"Four simultaneous Stunning spells… why!" Headmistress McGonagal said.
"Might as well have been a crippling spell, do you have a bed close!" Shanyrria asks.
"Through their why!" Minerva asks.
"For a witch, your… education is lacking!" Shanyrria said, "For my magic to work you can't move for the next 2 turnings of the sun!"
Reaching into her pouch Lily produced the required herbs crushing them in her hand and making an herb poultice.
Rhianon eagerly watched every step Lily made, as Shanyrria set about her work
"But the sorting" Headmistress McGonagall stated only to be cut off by Ginny saying, "Will be conducted by The Lady of Ynys Afallach!"
Minerva knew when she was defeated
Moments Later
"On your belly women" "Air do bhoireannaich bolg" Shanyrria commanded as she placed both hand on Minerva's back.
Headmistress Minerva McGonagall was unaccustomed to being treated this way, however, whatever Shanyrria was doing made her back pain disappear.
In a singsong elvish voice Shanyrria said, "Healing the body is easy enough, but you have to heal the spirit simultaneously!"
"Lily is my first apprentice since Cliodna, my tribe was exchanged as hostages and became what you know as house elves!" Shanyrria said with an undertone of sadness, "Have you ever seen what happens when you cage a wild animal!"
