If by dungeon you mean an area with lots of mobs, a ZEM and lots of loot, then No. That may sound fishy, but I am trying to be accurate.
Yep, I edited the reply to specify, but sounds like you got the gist of it Hmmm... so if it's not an outdoor zone, and it's not a dungeon... ... is it in a city?
Not illuminated well, perhaps because it is underground, or perhaps because it is in a swamp and the sky is always dark for some unknown reason I've asked a lot. I'm gonna go back and examine your answers!
