Overview
Finders Keepers is a secondary quest in The Witcher 3: Wild Hunt, set in the Skellige Isles. It is proximity based: if you find it and leave without starting it, it disappears.
What happens
On the larger island north of the Giants’ Toes signpost, where a ship has run aground, bandits are looting crates. After Geralt kills them, he takes a closer look. One crate bears the insignia of Clan Brokvar, and another holds a fine sword, the Solid Skellige sword.
In Svorlag on Spikeroog, the merchant at the docks explains that one of their ships sailed a month ago to raid the Continent and never returned. He asks about the decorated sword. If Geralt has it, he hands it over and receives a finder’s fee. If not, he is paid slightly less.
