So, I'm not asking if you made a Dremora who's somehow sympathetic to mortals in Nirn, what I mean is what ingame designs or tools did you find help you RP?
For me, I found Anvil's home to be very useful as a home for my former master thief. He owns the home in Chorrol (was going for Skingrad, but the Steward orc went missing so I had to make due) as his 'front' home, but in the chamber where Lorgren one was entombed, he stores his hidden cache of treasures and the Cowl of Nocturnal there, awaiting the day their heir finds the treasures. It's also where he 'buried his past' when he donned the whites and became a Knight of the Nine.
Anyway, what useful tricks/ideas did you find naturally? (Mods don't count)
