As far as I recall, I was in war against the humans who didn't believe us fairies anymore. This made me want to rule the fairies and humans. Ever since I left Morgana, I have created a team of my own called the Fairies of Vengeance. These fairies are vengeful in nature and personality. One of the fairies in my team is Layla, who joined me in hopes to get revenge on the Wizards of the Black Circle for the death of her boyfriend, Nabu.
We successfully locked away Morgana in a mirror and proceed to go to the Omega Dimension to go after the Wizards. Once that is done, we will take over the humans' world.
In the Omega Dimension, I discovered a secret that my former queen has kept from me all this time: Roxy, the fairy whom she takes an interest with, is her daughter. She manages to convince the fairies under my command to not go through with vengeance, leaving me and Layla left as the only members.
We tried to fight of the Wizards, but we're not powerful enough. Just then, the Winx Club shows up to defeat them.
Seeing Layla help really makes me want to help, too, so I joined with her friends to defeat the Wizards, freezing them in solid ice. Just then, we feel that this dimension is having a falling debris of ice.
Bloom attempts to fly, but she sensed something is not. She saw something that is not right. It's me standing in the middle of the ice.
"I'll stay here," I said.
That's right, I'm staying here. Now I have learned my lesson for what I have done to everyone, including Bloom. To atone for all that, I must die being redeemed.
"But why?" Bloom asked.
"I left the light for the dark side," I replied in remorse, and then I look at the Wizards who are now frozen in solid ice. "They made me so."
Bloom flies close to me. I guess she still wants to get me out of this.
"No, Nebula," she said. "You still have goodness inside you. You'll always have it. You no longer belong to the dark side."
These words have touched my heart. I feel it warm within me; it means that I finally found the light within me. Bloom is right, there's always goodness inside me. I cried happily of what she has to say as I grab her hand, ready to leave this dimension.
Back to Tir Nan Og, I bow to Morgana.
"My queen," I said. "Forgive me."
"Stand up, Nebula. Stand up, my friend."
Then she took me for a hug, and so did I.
Now I know there's always light within me.
