Some say the Albion created the Arnam out of Peloran base stock. Others think the Arnam came first. Whatever the case, the Arnam are genetically engineered supersoldiers, much like the Peloran, but they operate best under water. They generally sport slightly larger chests than most humans to fit the extra set of gills that allow them to breath under water, slightly longer arms and legs, and slightly larger hands and feet, complete with webbed fingers and toes. They would still pass for normal, if extraordinarily fit, humans were it were not for the dark blue or purple skin and the coal-black eyes that unnerve most people. The eyes are why nearly every Arnam wears a fancy set of shades when above water.
