The 4 vessels

The 4 vessels are part of the Forgotten knights dlc. They followed the knight out of the abyss when he escaped but stopped at the point when they got to kings pass and them and the knight split and started to wander away, and they tried to find a place were they could all be in peace, they eventually find the Undusted dark. In the event of them wandering, 2 vessels die (being broken vessel and the one in hornets boss-battle area)!
