The only thing of any real note in Gorst is Anzovin, who's located in the southeast corner of the town, in one of the two undamaged buildings in town. He sells alchemical ingredients, and also creates Undead in his spare time.
In the northwest corner of town is the other undamaged building, which used to be a barracks. The office in this barracks contains a few of Anzovin's undead. There are also some undead in the northeast and southwest corners of town.
