Umm, armor, weapons, special earrings, Nyanta gear, quests, almost everything?

Bar the normal key quests and what not, there are requests for both items and quests (Lots of them), which as stated already jump between Village and Gathering Hall during the same questline, meaning you have to do Village stuff to unlock Gathering Hall stuff, and vise versa.
