Morveth is found in a hidden cave at the northern edge of the Forgotten Deep. It is recommended to use either a Zepline Tube or Boat Tube to get there, then find either of the waterfall entrances.
Morveth will give you a series of quests, and will allow you to purchase Morveth’s Treasure Gun at the end. With a cost of $82,500, it is a great Harpoon to use towards the endgame.
