Deezelisk is a duke in the Underworld in Heroes Chronicles: Conquest of the Underworld. He is a powerful demon, but his rule is threatened by the fact that he is blind - a weakness that the other demons can exploit, once they overcome their fear of him. He was blinded by a knight many years before the game, after a failed invasion of Erathia. Queen Allison plans to present him with the Pendant of Second Sight, a magical artifact that can cure his blindness, and ask for his help to free her father's soul from the clutches of the demon Jorm.
