Kontaur can be a pretty dangerous place, but it's full of pretty cool eq and some nice Realms history. Aggro guards wander the castle and the balrog camp (and there's similar mobs called beastmen in the forest). The trickiest part is Carnifex castle, which is entirely no recall. Kontaur is also home to Wicorith, the simplest way to get to the Underworld. Aside from the stuff in Carnifex, the only run mob of real note is Sage of the Mountain. Chlith has some decent stuff that is easy to get too.
