Iniyasz, Ka'ash'du'Maal'Braid's Executioneer

The unknown warlock first appeared in 436 YoU when Bran Sparkhammer was escorting a captured cultist from Rivgraad to Eversted. During the journey in the Griffin Mountains the spellcaster suddenly appeared and shot the prisoner with eldritch energy before anyone could react.
As the escort charged towards him he summoned two Flamer demons and fought against Bran Sparkhammer who was first to reach him. As Yandrak and Ori managed to quickly dispatch one of the Flamer fiends they joined the fight against the leader. Deadly wounding Bran the mage had yet to use a teleportation spell to break contact once the other two started defending their downed companion. The servant of the demon prince yet managed to escape, his mission completed when he killed the potential informant.

In 438 YoU he appeared once more when a delegation of the Inquisition reached Rykthaven to deliver Bloddwyn's Book of Monsters to the owner. As demons of the Nameless One attacked the camp the servant of Ka'ash appeared next to the tent of the priestess of the Lady. With Bloddwyn Bluainach and Grand Executioner Robbaer van Nickels charging into the fray he once again summoned several Flamer demons that burned the priestess and her guards to crisp. Bloddwyn first attacked him and then the Flamer demons as he recovered his book, but the cultist didn't let him escape demanding the book to be given to him. The young monsterhunter was foulishly ready to protect book with his life, yet before he was burned to death by the fiends the Grand Executioner convinced him to throw away the book. The cultist destroyed it and disappeared through a portal.
Later that year when Rykthaven's town guard was leading the Cleansing to get rid of all cultists following the Nameless One, Bloddwyn got his chance for revange. Spotting the cultist in service of Ka'ash in a side street Bloddwyn managed to hit him with a bolt from his crossbow and marking him, yet before he could shoot a second time his pray was gone. Jhessa warning her friend of this feeling odd followed him on his hunt for the mage that destroyed the book of monsters. Finding his target in a small courtyard Bloddwyn soon found out that he was tricked into a trap.
The warlock laughed at Bloddwyn's naivity and casted a sphere of darkness on his sword before jumping the monsterhunter. Not able to see both Jhessa and Bloddwyn had a hard time hitting their target, but the cultists didn't seem to be affecked by the pitch black darkness of his spell. Hopelessly outmatched Bloddwyn was knocked uncounscious. Only the intervention of a msyterious woman by the name of Helna distracted the warlock long enough Jhessa to drag Bloddwyn to safety. As the woman attacked the cultist once again Flamer demons appeared. While running for their life Bloddwyn and Jhessa saw a shadow climbing a house followed by two of the fiends burning everything they touched. A few moments later Helna was burned alive, with no trace of the cultist left to be found.

During the Night of Demons in 438 YoU he appeared in Siglagthil at the Tier Breche's graduation ceremony. As he was searching for Rael Dulaenthan he teased the exalted glabrezu Thalos'Khulebin about the draegloth he fathered by the demon who was killed by a human and its head 'paraded on the surface'.
