Xtib was the organization that handled the creation of TibannaX, which served as fuel for starships. This unusual isotope of Tibanna found use in the engines of Jedi StealthX fighters, helping them to reduce the detectability of their ion trails. Its establishment happened near the conclusion of the Yuuzhan Vong War.
In the time of the Swarm War, Bornaryn Trading, guided by its co-founder Lady Aryn Dro Thul, acquired Xtib. This action was meant to communicate to Luke and Mara Skywalker that they had knowledge of the plot to murder Raynar Thul.
