Ramund’s Assistance

From the gate mechanism turn right (roughly north) and run up and into a cave at the edge of the garden. A few steps into the cave, you witness Morkvarg speaking to the skull of an old friend Ramund about a key he needs. Your objective updates. Though you can “meet” Morkvarg now, it is far better to find the key first.

If you lack clues, step into the werewolf’s cave, and slay this beast. Once he’s down, Morkvarg pleads for you to undo the curse. You can speak at length about his pitiful existence, Craven, a reward, and learn that simply slaying him doesn’t end his life. Morkvarg also mentions he eats his own flesh; it boils his tongue. Interesting. Finish him off, as you don’t have the wherewithal to end his life. While Morkvarg is temporarily dismissed from his lair, use your Witcher Senses to check the ground; there’s a draft from below.

Ramund isn’t much use (since he’s a skull on a pole), so return to the garden (having raised the right sluice gate), dive into the canal, swim roughly northwards under the gate, and enter a second cave directly under Morkvarg’s lair. Aside from a chest, there’s the rest of Ramund’s bones here. It seems he is useful after all—grab his key.

Swim back to the gardens, retrace your steps all the way back to the sacred oak, and investigate the chapter house behind the tree. After a thorough inspection, you uncover a chest with Morkvarg’s Journal. It makes interesting reading. Aside form Morkvarg’s despicable past, it implicates Einar!
