Well there is a wiki? I'm all proud and stuff for figuring out how the hell to edit the code to make a new page for something that wasn't entered in yet. Even if I took forever and a day. /puffs up
But yeah, they redid a bunch of stuff from Cora~Azteca and added a new Snow town with a bunch more quests. I didn't have to do mine PQ to level until I hit 195, and then I just did Swamp. The exp in the mines isn't as hax as it used to be, but I still have a char in range to afk at each one.
New Snow town is pretty. Even if it is still Snow Hell.
I don't remember if you were there when they added Abyss, either.
