The Call Of Kuliu

Check your Inventory menu and read the journal you found. You’re fortunate that the thief listed a possible location where buyers of the sword may be gathering—an old fortress near Fyresdal. Prepare for a bit of a trek (or boating expedition) to the southern coast of the island. From the town of Fyresdal, run up the path of deforested trees, and up towards the wooden fortification nestled below the snowy cliffs.

Enter the fortification via the only entrance, and fight the renegades. The now-familiar pattern of looting a journal note from one of the slain thieves is your next plan. Check your Inventory menu, and careful reading reveals another meeting. This one at the even more remote Whale Cemetery on the northeast coast of Ard Skellig.

It’s a long trek, either by boat around the coast to the Whale Graveyard, or over Arg Skellig to the druid encampment of Gedyneith, and then a northeast bolt down a slippery gravel path towards the ocean. Four swarthy renegades are waiting. As before, all must be put to your blade. Afterwards, the fabled sword can be found along with a journal, on the corpse of the thief leader. Head back to Kaer Trolde, find Olaf on the bridge, and present him with the sword for a small reward, as the quest concludes.
