Vaecta was a priestess of Yun-Yammka, the Yuuzhan Vong god of war, and was attached to Warmaster Tsavong Lah during the Yuuzhan Vong invasion. Wizened and elderly, Vaecta counseled Lah on the manner by which he should retain favor with the Yuuzhan Vong Pantheon, often advocating sacrifices and, on a few occasions, attempting to influence the warrior's strategy.
