It wasn’t fear that made him use the chameleon arch to hide himself away among humans. The Family of Blood were dangerous, certainly, but he’d faced far worse enemies and stood firm.
They kept following him though, with their stolen vortex manipulator, and he knew they’d never give up; wherever he went in time or space, they’d be right behind him. Hiding was his only option, but they hadn’t understood. They’d kept hunting him; even hiding hadn’t been enough.
He’d wanted to spare them, but they’d wanted to live forever, and now they would.
Be careful what you wish for.
