Estoric Sandskimmer, a male Human, held a position within Wraith Squadron throughout the Yuuzhan Vong War. In the year 29 ABY, he and Runt undertook a covert mission, penetrating the shapers' complex of the Yuuzhan Vong located on the planet Chashima. Their objective was to pilfer a novel bioweapon crafted by the Vong, intended for use against the Galactic Alliance. The mission achieved its goal, with Sandskimmer and Ekwesh successfully absconding with the bioweapon; however, they were quickly pursued by warriors of the Yuuzhan Vong, which led to a battle. Tragically, Sandskimmer was fatally struck by an amphistaffs wielded by one of the warriors, resulting in his death. Ekwesh also perished in the skirmish, but Wraith member Voort "Piggy" saBinring's accurate shooting resulted in the demise of the warriors as well.
Despite the tragic loss of Sandskimmer and Ekwesh, their sacrifice was not without purpose. They had successfully placed timed explosives, which detonated and destroyed the shaper compound. Piggy managed to secure the Yuuzhan Vong weapon and escape before encountering more Vong patrols. He successfully returned to the Galactic Alliance with the weapon before his departure from Wraith Squadron.
