Hi,
You're welcome to work on adding more lore to the wiki, that would be great!
Right now it has the "official" history of the world
here, and some for the dieties and races. Also the cities have a little "unofficial lore" (originally from EQAtlas). But individual mobs don't have much.
I look over most changes so I will let you know how to fit it in best with the current style of the wiki, if need be.
