environment: theme:

A lump of weathered timber
An oar made from sharkskin
A piece of copper with a drawing of a lighthouse
A bleached shard of bronze
A seal pelt decorated with sigils
A shrouded piece of copper signed by a merfolk explorer
A slippery hunk of obsidian
A petrified lizardfolk tongue
A cracked bell from a shipyard
A slimy wooden plank that attracts tiny crustaceans
