I didnt put this into the intro because I wanted to make a longer post but didnt have the time yet, plus leave a bit of mystery:
During the period of inactivity Aka all the spirits were sleeping, the building was bought by a Seer, who actualy never visited it. Eventualy she died of natural causes under suspicious circunstances and left it on a will for her relatives and hence we have the quest.
The city we are in it's just known as city both because I am lazy and in the old times people did a magic ritual to hide the name of the place, so it's citzens could escape the effects of a curse. Due do it, no one knows the name of it (however they can somehow understand when they are talking about the city). Normal people arent aware of this effect, but magic users are - some of which died trying to discover the city name.
