Dangerous Sometimes. Malicious All the Time

After finding the Craven in the well of Freya’s Garden, and speaking about locating (and finding) Ciri, Yennefer requests you meet her in Larvik, at the warrior’s hall. She has something important to tell you. You can accompany her to Larvik immediately (on horseback), or agree to meet her there later (so you can prepare or finish other quests first).

Enter the warrior’s hall, where Yennefer is gaining the upper hand on some unruly yokels. Speak to her, and she mentions a man named Amos var Ypsis, a specialist on djinns. She tells the story of his disappearance. Answer how you wish. She wishes to know what became of him, but she’s particularly interested in his djinn. Feel free to ask more about these mystical creatures, before agreeing to help.

The harbor is a short jog from the warrior’s hall, down the hill to where her vessel is moored. Speak to her again. She tells you of an incantation on her boat, allowing you to see if there are any wrecks on the seafloor. Yennefer takes the helm. You sit at the bow of the boat.

You set sail into the ocean waters, talking of past adventurers. Eventually you reach an area that Yennefer wishes to search. She casts a spell to slow your heart, allowing you more breathing room. Leap into the frigid waters, and dive directly below the boat. If any sirens are in the vicinity, shoot them with your crossbow or magic before you go.

Below are the remains of a longship, and a few swimming drowners. Avoid them as you find the entrance to an underwater cavern, or use your crossbow and remove them as a threat, and swim inside (roughly east). Use your Witcher Senses on the small half-buried vessel—it sports a Clan Drummond figurehead. This isn’t the correct boat, so swim back to the surface.

Yennefer sails roughly northwest, crossing the ocean toward a pair of small, odd islands of thin fur trees and rocks. Before you reach there, watch for the white whale if you wish. She then stops and finds another wreck. Dive down and discover a variety of chests and barrels. By the rocks and ship’s deck, you find a war horn bearing the Clan Heymaey symbols. Check for further chests, and gather all the war booty you can from them. There’s also a Skelliger’s buckler from ages past. But this isn’t Yennefer’s boat. Return to the surface.

Yennefer continues to travel towards the two islands that make up Ingdalen Isle. As she passes between the rocks, she senses something odd. Dive down under her boat, and you’re astonished to discover a huge crater! However, when Yennefer uses your eyes to see this unnatural seafloor, she informs you this anomaly is the effect of teleportation. Now swim toward a collection of chests and crates (which can be looted), before finding the remains of a boat. Near here is a basket cut exactly in half. Close to the boat is something more. A broken seal! Yennefer orders you to the surface.
