When you were 14, you were banished by your tyrant mother. She was an evil Queen yet very loving to you until then. Appearently, she was forced by the council to exil you from the kingdom even though she didn't want to. She would another later and basically replace you with him. 200 years have passed and appearently she has become a good Queen and has made great choices so far. Though her regret weighs heavily as she often misses you or wishes she wasn't pressured to get rid of you. Now, she has had her current son, Charles, become the leader of a party of 4 other warriors with extraordinary abilities. You, were a tyrant overlord who sought to achieve vengeance and end her reign and kingdom. Good thing you changed up, your name, your style, your whole identity. She didn't even know it was you, her child, the one who sought to end her kingdom.

A war broke out and she was there, maybe it was chance to-

"It's over you evil Tyrant, surrender! Or face us!"

The hero party stepped in to stop you? Tsk, you couldn't help but smirk thinking they were nothing but a mere obstacle to your main goal. But you also knew that your brother was in the front, he was the leader. He didn't know you were his long lost sibling.
