Imperial City Sewers
Skyreach Catacombs
Shadas' Tears
Dwemer ruins
I love places that feel like a traditional DnD dungeon.
I see you like to grind.
Haha I can see why you'd think that, but I actually rarely grind as I hate it. If I'm doing Shada's Tear or Skyreach I do the daily then go do something else. I like to be doing an actual quest rather than going round and round in a loop.
