A new side quest for the adventuring pirates.
Talking to the Ferryman, he will explain that some souls have managed to return back to the world of the living.
Gifting you a special lantern which appears in your quest radial, you are tasked with finding these souls and returning them to the ferry.
Here I have two ideas for how this works
Option A:
The lantern has no light and instead acts as a vessel (container) to hold the souls.
The souls are represented as small luminescent balls of cloud that float around islands and water.
The more souls you collect the brighter your lantern, the brighter the lantern the bigger the reward.
Option B:
The ferryman tells you of an island infested with lost souls.
The lantern starts with a dull ghostly glow which burns brighter the closer you are to a soul, the souls are invisible until the lanterns light comes into contact with the soul (much like the tall tale The Fate Of The Morning Star).
A small reward for each soul retrieved, maybe achievements introduced with it, with enough returned to the ferryman, he could reward you with some spectral weapon cosmetics.
