During your travels (if you followed the guide above) you will have found a disabled gatekeeper in a small side area in the south-western part of the large lake in the Fjord.
You will need to return here once you have received the Maker’s Key from the boffins at Tri-Forge (just before The Lost Temple run). You can use the key on the gate keeper to activate him. This will complete the quest. It turns out his name is Oran and he needs your help!
He will give you another side-quest – “Wandering Stone” and Oran’s Heartstone Fragment.
