Misshka

Misshka is Grey's familiar. She is a little shithead of a sprite that spies on people, flips them off, generally causes mischief, and absolutely will bite if provoked. Fair warning, she's easy to provoke.
Misshka used her heart sight ability on Vahlka and apparently told Grey that she was "evil and not to be trusted." but Deacon disregarded this and tried, in vain, to convince the rest of his party of that point as well.
