Contract: Here Comes the Groom Witcher 3: Wild Hunt Quest
Suggested level: 19
Group: Witcher Contracts
Location: Skellige
You can start this quest by reading the "Nils' Disappearance" contract posted on the Svorlag Notice Board or by visiting the Sirens' Cave.
In Clan Brokvar's village on Spikeroog Geralt took on a search-and-rescue contract. Kevan, the man offering the bounty, claimed the missing man had developed cold feet and fled from his betrothed, yet the woman herself - Britt - insisted her lover had been snatched away by a monster.
...or, if you started the quest by going directly to the cave:
During his time on the isle of Spikeroog, Geralt came across a cave in which he found some unusual tracks. Suspecting a monster, he decided to look into the matter.
