Until very recently, the Hirschtempel ("Temple of the Stag") was a long-running temple of the Horned Man which also doubled as a brothel. As more and more "respectable" and "upstanding" citizen moved to the area, many of the newcomers perceived the temple as an affront to their moral sensibilities. Thus, when the owner and proprietor of the building recently suffered financial difficulties and was forced to sell it, a priest of Thenos was able to purchase it with the aid of some wealthy donors. He wasted no time in kicking everyone out and is now in the process of rededicating it into a temple to Thenos.
Needless to say, this doesn't sit well with the old priest of the Horned Man and his followers, who are now looking for some way of revenge as well as reestablishing their temple.
