One day, I noticed Grelka was repeatedly missing from her Riften stall. I knew I might be able to find her by using a command to place me at her. I assumed she must still be alive as attacks on NPCs usually happen when the player is around. Or, always happen that way. So I used the command... and spawned http://tinypic.com/r/ifucls/6 . I can't describe the chill that went down my spine! What is this place?? It contained a mound of random named bodies as well as 3 living NPCs, two of which I had to resurrect at some point, the third I had no recollection of, as well as two coffins, Lu'Ah's and Ralof's, containing a plethora of items, all of which constituted stealing. I thought the mound of bodies were all the named NPCs who died by mine or someone else's hand at one point or another, but that's not the case, as Aerin is missing, for one. (Grelka, however, was there, dead - but I know she was alive last time I visited Riften)

Isnt that heaven or hell? where all dead bodies go?

Looked pretty twisted to me, with 4 pitch black doorways, leading only back into the tiny room. Yep. Hell.
