Heu Jhazsman was a human noble by birth and a former member of the Greydance. As a part of his induction into the Greydance, Hue made a pact to serve Zargon in exchange for a portion of the great old one's eldritch power. After being framed for this father's assassination, Hue left the Greydance and secluded himself in the Neverwinter Woods. He only came into the city to maintain his supply of hard liquor.

 
After some time in the Woods, Heu began to hear the voice of Zargon calling to him. "You know they did it. You know they killed him." Heu always knew deep down that the Greydance were responsible for his father's death. Being drawn from the woods and into the city of Neverwinter. Heu took a job protecting a wagon on it's way to Phandalin.

 
From that day forward, Heu was an adventurer, a hero, and kind of a jerk. Protecting the weak and striking fear into the hearts of evil men, Heu's frightful Eldritch Blast can strike an opponent from a frightening distance. Now free of Zargon's servitude, he and his familiar Gassier adventure with The Party into the Forbidden City of Omu. Eventually, once the Soulmonger is destroyed, he hopes to track down the Greydance, stop them from awakening Zargon, find answers about his father's death, and finally exact his... "REVENGE!".

 
Heu is a Warlock of the Great Old One, how made his "Pact of the Tome" with Zargon. His Familiar, Gassier, is an Imp who also broke free of Zargon's servitude.
