I made a sticky thread. "Custom Lore" is anything that isn't a character bio. From my experience, when people start writing a biography, they may come up with all sorts of creative ideas. The "Custom Lore" section is there for any creative piece our members come up with. Unlike the biographies, they don't need to be approved. There is no recommended structure. And they likely won't become the official lore. It's a place for anything and everything.
No, a biography will always be yours - you are free to edit it continuously. There may come a time when we decide to put some of the biographies ingame, especially for donators. In that case, what may happen is the book ingame may become outdated if you edit your biography very often.
Alright, good to know. How would you keep people from saying their a farmer on day and a baker the next?
I expect people to be sensible enough not to change their biography dramatically, especially once they know it has been put ingame. When you first write it and decide to change it the next day, it shouldn't matter that much.
