Tjolnir the Super-neat is a promoter in Might and Magic IX. He can promote Initiates in the party to Healers.
Tjolnir can be found in the Fre's Spirit healing temple in Guberland City. He gives the party the Heal Nutty Nurtigan quest, which requires them to find a cure for Nutty Nurtigan's curse. Tjolnir tells them to find Skarphedinn Njalssen at the Eye of Newt apothecary and ask him to make an antidote.
Skarphedinn needs a lock of Hjordisa the Hag's hair, so the party must go to her and get one. Hjordisa refuses to help them, but the party can steal her hairbrush. When they return, Skarphedinn makes a potion that can cure Nurtigan.
Once the party has healed Nurtigan, Tjolnir will promote any Initiates in the party to Healers.
