Disclaimer: I do not own the Thundercats, nor the Phantom of the Opera, where the title of this plot bunny came from. Thundercats is owned by the company that made it and Phantom is owned by Leroux, Kay, ALW, and all the other people who have made a profit off of Phantom.

A/N: This is an early fanfic idea of mine that I started a while back, so don't be surprised by the tone of it. If there are any mistakes, I apologize and will gladly correct them. It starts out early in Liono's childhood, then past the events of the show.

Music of the Night

"Daddy, where's Mommy?" a 2-year-old Liono asked his father.

"She...She's gone, Liono," his father, Claudius, replied, his face showing his grief.

"Where did she go?"

"To a better place, where she won't be in any more pain, son." Claudius looked at his only son and gave him a hug, with a few tears running down his cheeks.

26 years later

"Is anyone there?" Liono opened his eyes and tried to sit up. Pain shot through his side, so he laid back down, frowning.

"Liono?" Panthro looked in to find the young-well 28-year-old Lord of the Thundercats awake. "You're awake! We almost lost you."

"How long have I been unconscious?"

"2 weeks. You had us worried. It was touch and go."

"How's Kit?" He was worried, as he remembered she was due to give birth soon.

"She's fine and so are the twins."

"Twins?"

Panthro struggled not to laugh at the expression on Lion's face. "Your son and daughter were born last night."
