As Dundee said.. I have downloaded numerous fixes from Baldurash as well, and after that the Guarded Compound was linked as a stronghold of Slave Lords (linked to initial Copper Coronet quest with slaves), and from there it was further linked to Twisted Rune. Not a bad idea as such, some big organized criminal organization. It's sort of tied to Bridge District tanner as well I guess, since you will be attacked there by Rune Assassins and such..
Basically while there's no "in-game" quest as such, take it with the realization that it's, or was, a big organized crime conglomerate and you single handedly - or with a party - just put the lights out of them
