Caoimhin Shan was the son of Jorno Shan and Kando A'Tome, and the older brother of Eliana Shan. He was a Jedi Master, an honorary member of the Emerald Order, and the Grand Master of the New Jedi Council, also known as the New Jedi Order or the NJO. The alliance of the NJO slowly drifted apart, and soon Caoimhin was the only member left, leaving him as the only commander of its fleet and the sole defender of the Jedi Temple on Haruun Kal, as well as the planet itself.
