My guess, is that they will probably keep that pretty quiet right up until the MUD and exposition, cuz world building from that point is going to be a huuuuuge chunk of starting lore. Also they have more mechanics stuff to cover. Cannot wait until our next look at female aging/body morphs/animation. :o

The MUD will be the recent history. As for the Lore/ancient history, they have said they want to keep it fairly secret since they want people to learn the Lore/history from the game.
