Sprint past the sacred tree, drop down heading northeast, up some stone steps, and into an overgrown grassy stepped courtyard where there’s a wolf to cut down. Then head to the edge of the raised garden and look down onto a lean-to and small canal.
Drop down from the lean-to and check the following with your Witcher Senses. There are many prints both old and new. Morkvarg’s lair is close.
Climb the stone ladder embedded into the wall, and clamber onto the higher ground overlooking a sluice gate and two levers. There is a ruined bridge in this area with a locked gate on the other side.
You can’t reach that to continue, so inspect this area closely. Utilizing both levers should allow you to open the flood gates. Save your progress, and start yanking those levers!
- The left lever changes the gears of the mechanism to lift up one of the three sluice gates. You can see which gate is able to be lifted by watching the three wooden mechanism dowels move up and down between the two levers. Simply use the left lever until the sluice gate you want is ready to be moved.
- The right lever moves the actual sluice gate you have chosen. There are three gates:
- The left gate opens a watery exit outside, and out of Freya’s Garden, if you wish to leave easily.
- The middle gate allows access to the further part of the gardens, where both a well and a secondary structure is accessible; to further this quest.
- The right gate is under the waterfall, leading to an underwater cave where a key can be found. This is critical during Secondary Quest: In Wolf’s Clothing, but don’t head there yet; raise the gate in preparation before continuing.
Once the right sluice gate is open, you can continue.
