I heard of a long line of necromancers by the name of Conkade. i asked this question previous and a few got the question mixed up. im not asking about necromancy, i know what it is and i know its considered dark practice. Im asking if anyone has heard of the family themselves, if there is any stories/lore that you may have heard. Possibly families that have a longer linage will possibly have heard of them. All i know is that they were well known Necromancers, and the family predated the witch trials. im just trying to find out any other information about them. the family themselves interests me greatly. again, the Conkade's are "they" not "him" which was some of the confusion in my last question. thanks for any help you may have.
