Gaithel, who lived on Yungbrii, was the sibling of Sela Trune, an officer belonging to the New Republic Security Bureau. A month following Trune's departure to become a member of the New Republic, Gaithel and the rest of Trune's family met their death in a skirmish when the Spice Runners of Kijimi found themselves trapped on their family's farm, resulting in the deaths of Gaithel and his family at the hands of the smugglers.
