From the bridge leading south out of Thorshafn, follow the river going southwest. Keep going until you see an area on the right that looks like a burned down forest. In this area, there will be a section of raised ground that you can only reach by going through a hollow log.
On this high ground, walk out onto the dead tree that hangs over the edge. From the tree, hop down onto a tree stump.
Carefully leapfrog between the nearby stumps, go up the branch on the last stump; you are now in Silveroak's lair.
Access the high ground through the hollow log.
