Orm Marius had a meeting with the Fishermen King Ricou and tried to persuade him into joining him in the War for Atlantis, but he failed. Orm then killed Ricou, coercing his family to join him in the war.
The Fishermen have fish-like characteristics such as scales and a tail, but have human-like hands, faces, and bodies. They have green blood, and they do not have any hair on their body. While they can also breathe air alongside water, their bodies are not designed for movement on dry land.
