Circle of the Crimson Abyss

When one thinks of druids, one normally thinks of the deep woods, forbidding mountains, thick jungles, or other landlocked locales, but druids are found not only on the land, but also sailing the high seas of Scarn. Some adventure with pirate and privateers, others explore the sea for many reasons known only to them, and the creatures they commune with beneath the waves. Regardless of reason, their usefulness on board ships made of wood are undeniable and their company most welcome on board most ships. There are of course exceptions as some druids pursue darker goals such as finding ways to harness the power of the titan blood infused in the Blood Sea.
