The Djarlik are a former client race of the Yu'vath. The Djarlik were aquatic xenos and spent generations practising three-dimensional combat. This made their transition into void warfare smooth and intuitive, and the Djarlik proved themselves to be expert pilots and tacticians. During the Angevin Crusade the Inquisition deemed them a threat and the species was purged. There are no known remaining Djarlik and their eradication is one of the many successes linked with the Crusade.
