The Mad and Dangerous Depths

Journey south via the wilderness pathway that winds past the Old Watchtower, and down to the southern shore. Or journey by boat. You’re looking for a cave opening guarded by a gaggle of sirens. Slay at least three before entering the cave system.

The place stinks of carrion, so prepare for combat with six drowners as you progress down the initial tunnel. This widens into a waterlogged chamber, where a towering primitive altar to the deity Melusine catches your eye (especially if you use Witcher Senses). Turn and head down the southeast tunnel.

Locate the following:

• Odd scales on the altar.
• Siren tracks from a particularly large specimen.
• Scales showing an odd coloration for a siren.

Follow the tunnel, pausing only to climb the right-side ledges and leap to find a treasure chest if you wish. Back in the tunnel, turn the corner to face a great fissure. It seems the old cult of Melusine that used to congregate here prayed to an ancient ekhidna.

The trail in the giant fissure cavern picks up again, as you pass some floating barrels ripe for an Igni explosion. Detonate them if you wish, as three more drowners appear to thwart you. Follow the tracks to ledges on the south side of the chamber, leading to exterior cliffs. Crouch down and examine the corpse of a man lying face down. It is Nils. He’s been dropped from a great height.

Something screeches overhead. Britt wasn’t lying. Face the mighty Melusine in combat!

End: After Clipping the Wings of Melusine

After slicing sections of Melusine to satisfy Kevan’s curiosity, journey back to him and explain what happened to Nils. He hopes you might tell Britt, which you can accept or refuse. Choose the former, and she is on the clifftop. Tell her, and she vows to be true to him for the rest of her days. She also hands over a reward for believing her (which you can accept or refuse). The quest then concludes.
