The Craydaxians were a sapient, aquatic species from the Southern Ocean of Primordius Magna, renowned for their skill in blacksmith work. Although once abundant all over The Southern Ocean, and much of the Southern Island Archipelago, the Craydaxians now inhabit but only one island in the whole archipelago. As a result of matoran encroachment, and the diseases vectored by the matoran, the Craydaxian population has dwindled to a mere five individuals.
