Tarellians

The Tarellians (sometimes spelled Darellian) are a xenos species of which almost nothing is known but who serve as mercenaries for the T’au military. Tarellian warriors are often called “Dog-soldiers.” The Tarellians were originally a part of the stellar empire known as the Tarellian Civilisation, which existed to the galactic north of the Ghoul Stars and coreward of the Kiltor Sector. According to certain Imperial legends, Mankind virus-bombed several of their worlds during the Great Crusade, at some point in the last two centuries of the 30th Millennium. The Tarellians seem to bear a grudge against humanity for the ancient assault to this day, as they aggressively reject the company of all humans.
