Elysium

She'll do anything to protect her family and kingdom. If it meant sacrificing her glamour and leaving behind the only home she knew, forever, to keep the Forgottens from interfering with the other Realms, she'll do it.

He'll do anything to protect his sister. She means everything to him and the one person that would hurt him to lose. But when she gives herself up to the enemy, in order to protect their world, he'll risk everything to get her back.
