Kernobee is a level-28 goblin quest giver found unconscious in a small room off the far (west) side (opposite the Clean Zone) of the Dormitory area of Gnomeregan. His room is on the bottom row, the 2nd doorway from the left (north) wall.
When he found out about the involvement of the Dark Iron Dwarves in the making of the super rig, Kernobee wanted to get out of Gnomeregan and report to Tinkerwiz in Ratchet as soon as possible. He got caught by the Dark Irons and thrown into the Dormitory to die amongst the stinking troggs. Adventurers can escort him out of Gnomeregan.
