The Sunstone is a main quest inside Battle Preparations. It starts when the ship reaches Skellige. Eredin travels between worlds on the Naglfar. To pull him back and cut off his escape, the mages need a legendary elven artifact called the Sunstone. The druid Ermion points Geralt to people who know the old elven ruins. Philippa Eilhart then helps Geralt find the stone in an ancient crypt.

Choices

The start depends on who rules Skellige after King's Gambit. With Cerys or Hjalmar on the throne, Ermion has gone to Madman Lugos, and the visit ends in a fight. With Svanrige as king, Ermion is at Kaer Trolde. A meeting there turns into a battle.

Ermion names two leads, the skald Eyvind and a band of pearl divers. Eyvind refuses to help if Geralt's reason sounds like a threat to the elven ruins. The pearl divers then become the only lead.
