Welcome to Baradorn!
The name is a combination of the elvish words for "tower" (Barad: pron. bahr-ahd) and "tree" (orne: pron ore-nay), becoming "Baradorn" or "tower tree." And right now, I'm playing on 30 levels of "dungeon" goodness inside it. Honestly, I was trying to find a way to do a megadungeon that wasn't underground. Now I just have to fill the freakin' thing in. Damn this A.D.D.!
