so would a thief of void dislike the spotlight, could a thief of void struggle with the abilities to become "irrelevant" ? I've seen plenty of theories that a thief of void will eventually become irrelevant as they continue on there journey, do you agree with this theory? and is the reason why Roxy doesn't struggle a lot with irrelevance is because she gives it away ?

Void is more than Irrelevance. Sure they can get so irrelevant they fade completely, but like. They could also just steal away the secrets from everyone and everything, or drain the Horrorterrors’ powers. Also, Roxy does struggle with Void- Alcohol. In a way, being the Voidy one sort of lets her be the Voice of Reason and the one that gets Stuff Done in the Session when everyone else is dealing with Awkward Teen Drama, soooo. In that context, it sort of plays in her favor.

Her taking of Void, also, manifests not in becoming Irrelevant, but literally Intangible and Invisible, which is a cool power in general.
