One Of my charecters is a level 10 Thief. She working through the Thieves Guild quests but I really want some good side quests.

I would prefer not the Dark Brotherhood because my Thief character tries to avoid killing if possible (thats why she sneaks around). It doesn't really fit with the charecter to be dispatching for gold and fame.

Shes also into alchemy but not that interested in other magical arts.

I've not many quests but blood ojn the Ice is a good one for improving lockpicking and general sneakery
