Glory To All Heroes!

The eastern coast of Ard Skellig is forboding, with jagged rocks and a variety of terrifying foes (such as sirens) to face. But venture here you must (via boat if you wish a little more safety), looking for an inlet with a short jetty, relatively close to the Distillery signpost. By the jetty and small boat is a campsite where two pirates are setting upon a Skellige warrior. Help the warrior out by defeating the foes. Speak with the warrior, who is out searching for his sister. She was kidnapped by pirates. Agree to keep an eye out for her.

Kurisu’s whereabouts are somewhere on the eastern island of Hindarsfjall. Plot a course to this wayward isle, heading for the southwestern shores between Lofoten and the Isolated Hut.

Locate the tiny island off this coast with a wrecked longship wedged into it, and swim or boat your way to the shore, where six sirens attempt to thwart your progress.

After a protracted battle, slay your final siren before inspecting the island using your Witcher Senses. You find slain sailors, some which have had their wounds dressed. But the real find is a note inside a chest, on the deck of the wrecked ship itself. It is a missive from Kurisu.

End: All Glory to Freya!

It seems Kurisu may be a priestess in the service of the Goddess Freya. Wade onto the shores of Hindarsfjall, and continue roughly northeast from your current position, and enter Freya’s Garden. You may have visited this place with Yennefer, during Main Quest: Nameless. Optionally try clambering about the walled gardens if you wish, although a path to the east leads you to Kurisu’s location—a cave mouth to an altar chamber and location of a shop. The missing woman is here, and explains how she escaped the pirates, and her debt to the priestesses of this sacred grove. She vows to be reunited with her brother as this quest comes to a close.
