The Kraler Draconians are a genetic norn breed made by Grendel Man. They are amphibious, and quadrupedal most of their lives. They are able to eat detritus, and thus able to get all nutrients from crobsters. They age slow, reaching adolescence somewhere around 30 minutes. They use the sprites of Draconian Norns, Bondi Norns, and Desert Ettins (tail). They are available from Grendel Man's section in the Norn Adoption Center.
Recently, Grendel Man has made V1.2 of the kralers. The V2 Kralers use only the Draconian sprites, amongst other changes. This new version is at KnyteTrypper's C3/DS Nexus.
