I don't know if this has been suggested already, but I think it would be a really nice addition to the game to have day/night cycles in haven. Yes, I realize it would have to follow server time which may be different for a lot of players, but it would add something extra to being in haven.
Heck, it's one am my time and it's still bright and sunny in Haven. Thoughts?
