Well, as far as the structure itself, it's purely a fairly large Ayleid city. It has been cleaned up, but it's not like the vampire lair which had been lived in for thousands of years. This one does show the wear of time, especially in higher up places. They do bring in furniture and such from the outside, which would bear Imperial and Nordic influences. In the lower floors, there is a sort of underground river that flows through a few chambers that serves as the city's water source. Beyond that, it's pretty much just an Ayleid ruin.
