Tubjub was the khan of Hyu-Ji, an island mostly inhabited by Sea Orphans in the Wushanko Isles. He was not an orphan himself, and lived in a shack to the west of the island. He cared little for the orphans, and formed an alliance with a group of Mercenaries called The Lost Men and the Soothsayers to kill them. He served as the middle-man in the deal, hiring the Lost Men to kidnap the orphans, killing them himself, and handing their organs to the soothsayers, who were seemingly unaware of their origin.
