Horn of Hockessin: A magical horn that can summon demons of various kinds from the Assorted Hells to do the horn blower's bidding. Or, if the demons are in a bad mood, to devour the horn blower. One must be cautious when blowing horns at demons. Created by the legendary demomancer Hockessin the Unclean. Most recently found in the possession of Isogoras the Xornite.
