Blue Warriors are an order of powerful warriors from the ice realm of Bluegrad, near the North Pole, who also drew their strength from their Cosmo. Their order was formed centuries ago after a Holy War between Athena and Poseidon, when Athena sent Saints to the North Pole with the mission of guarding Poseidon's soul resting place. Based on the research of Aquarius Degel in The Lost Canvas, the Blue Warriors are the descendants of those former Saints.
