As a group, the Agori-Kal are a small, tightly-knit band of freedom fighters, dedicated to the preservation of civilization throughout the Riptide Alternate Universe. As a species, they consist of three Agori and a single Bone Hunter, all of whom were mutated by exposure to 'Kal virus' and thus are generally referred to with the suffix '-Kal' at the end of their original species name. They are the main protagonists of the Protosteel Saga, which chronicles their adventures prior to the Reformation of Spherus Magna.
