What is the best house for an evil character? I do not have the Vile Lair DLC, only Dunbarrow Cove and Frostcrag Spire and those do not really suit my character well.

Benirus manor in Anvil has got a pretty evil looking basemant.
The rest of the house looks pretty evil before you complete the quest.

Bravil or the Imperial Shack both do a good job for the less noble evil guy.
But i'd probably say Benirus Manor too, for the eerie factor that the basemant brings.

Then get the Vile Lair... seriously, its perfect for the morally corrupt, has a nice armor and weapon.

Me three for Benirus Manor. :goodjob:

My evil guy is living it up in Skingrad, blending ya know? But he's more of the mafia boss type evil, puts on a shiny clean facade but is really going at it behind the scenes, for your more cult evil Benirus manor is sweet, the IC shack on the waterfront is great for petty evil doers, thieves/pickpockets and the like.
