I'm fairly certain I must have done some part of the chain to unlock him while leveling and then abandoned the remaining quests that put him in Klaxxi'vess but sweet baby Jesus in a manger wearing a tuxedo t-shirt I CANNOT FIND HIM AND IT'S DRIVING ME MAD.
Apparently he spawns after the completion of "Mazu's Bounty" in Soggy's Gamble. He is not there. Assuming there is no where else he would be besides Klaxxi'vess or Soggy's Gamble, logic dictates that I have not yet completed Mazu's Bounty. However, the three quests prior to "Mazu's Bounty" ("Kypari Zar", "The Root of the Problem" and "Fires and Fears of Old") all appear to be completed as well as I went to the coordinates that the quest givers are located and have no quests available.
Anyway, if someone has a suggestion I would be in your debt. It's really eating away at me.
Or perhaps since these are Mantid quests, it's just....
