Harrison Jones appears as one of several daily npcs who can visit your garrison. He will offer six quests as part of the Master Relic Hunter achievement.
The Lost Goblin
Fly to Nagrand and kill the ogres of Broken Precipice until you retrieve five journal pages.
The First Piece
Gutrek’s pommel is sitting in the eye socket of a large skull lying at the bottom of the nearby bone pit.
The Second Piece
Head towards the serpents in the Marshlands and find the hilt under a spiral stone.
The Final Piece
You’ll find the blade sitting on the top of a column located around the Ring of Blood.
The Spirit Forge
The Spirit Forge is located in a cave within Earthshaker Gorge. First click on the furnace, then anvil and trough to reforge the cleaver. Fight Gutrek and retrieve the weapon. Hearth back to the Garrison.
Hand the quest into Rokhan for your 150G reward.
