I think I’ve figure out why they are the eyeless hand

Given how in this season Brennan has been making ye extraordinary out of the ordinary and really playing on the name of things, I think I’ve figure out why they are called the “eyeless” hand.

My guess is that they are magicians of some sort and specialize in sleight of hand. The name is drawn from the part of a magic trick where the performer distracts you so you aren’t looking at the hand doing the trick. While you aren’t looking that had has no eyes on it, hence it being “eyeless”.
