Croire
Croire is basically a tome—think of it like those reality-warping books you see in the series. The main difference between her and similar entities is that while others can just peek across dimensions and link up with their alternate selves, Croire can actually travel between dimensions herself.
She's not really a villain trying to destroy everything. More like she gets a kick out of watching chaos unfold and poking the hornet's nest just to see what happens. She's an observer with a mischievous streak who meddles for entertainment rather than any grand evil plan.
