Sithik Ints is one of the many members of the Humans Against Monsters (H.A.M) cult. He is featured in the Zogre Flesh Eaters quest, when he turns the Ogre populace of their ceremonial dance enclave, Jiggig, into zombies, using his necromancy skills (which Malignius Mortifer informs the player of). During the quest the player gives him a potion to turn him into an ogre for his plot, whereupon he reveals the secret to making Relicym's balm and Brutal arrows. He can be found in the west bedroom of the second level of the building in northern Yanille (North of the Wizard's Guild).
If you try to steal the cup of tea from on top of his drawers, he will shout at you and tell you to stop. If you try to telegrab the cup of tea, he will call you a telegrabbing fiend.
