Gralik Durr was a Xindi-Arboreal who lived at an Arboreal colony. He worked at a kemocite production facility, and had been its primary technician since 2111. The colony provided kemocite for a variety of clients. Gralik took great pride in his work, often insisting on checking and rechecking that the kemocite was pure enough for whoever had ordered it. He refused to let his work be corrupted, however, by selling kemocite to weapons manufacturers. Gralik was fond of taking long walks in the wilderness outside the colony; he sometimes hunted tree scarabs.
