Für das Ende eines geheimnisvollen Tals.
At the end of a valley you row by boat through a small tunnel and get into the Totenschädel valley,
there you can find some ruins of a past settlement, which are already overgrown and a lot of lava.
Finally the skull, which I had finally gotten after several attempts a halfway good one.
There’s a door under the skull that might lead into a temple. But for me, it’s just an empty room.
