Hello! I own the temple in skaljard and I don't know if this is a feature or a bug so I am making a post here on the forums to clarify since it hasn't come up !
Ownership of a shop in the guildhall of Skaljard Temple grants access to the back room and quarters, I am not sure if this is a bug or a feature as unlike other guildhalls, access to the shop management is not locked behind any doors; just curious for security reasons if shop owners DO get access to the quarters and back room of the temple or not.
