You enter an alchemist's lab. The lab is a large structure on top of a hill, similar to that guy who is the genetic-altering guy from south park. He has some specific quests for you. I dont want to go into any detail since I cannot think of any...
But also in the alchemists lab there are several freaks of nature that you can find in various rooms (the freaks cannot leave these rooms because of barriers). These freaks can be fun to level off of.
I dont know. Just sounds like a fun idea.
