Koro Ziil

Koro Ziil, also known as the Hidden One and hu'aac-du'ul-staranjan—which, translated from his native language to Basic, meant "the one who dwells in darkness"—was a male Force-sensitive Kel Dor. He was a member of the Baran Do Sages, a group of Force-sensitive Kel Dor on the planet Dorin. He was one of the few Baran Do to be trained in combat, and became the Master of the Order. Ziil trained Baran Do Sage Charsae Saal, who would become the senior combat instructor at the Baran Do temple. In 34 ABY, Ziil also taught many Baran Do Force techniques to Jedi Knight Jacen Solo, who had spent the last five years traveling the galaxy learning among other Force-based organizations. By 43.5 ABY, Ziil had become the leader of the Hidden Ones—a secret sect of the Baran Do tasked with preserving the Order's knowledge. The Hidden Ones lived in a series of caverns deep below the surface of Dorin, where they could remain hidden from the rest of the galaxy.

In 43.5 ABY, Ziil met with Jedi Grand Master Luke Skywalker—who had been recently exiled for failing to prevent Jacen Solo's fall to the dark side of the Force and transformation into Darth Caedus—and Luke's son, Jedi Knight Ben Skywalker, shortly after becoming the leader of the Hidden Ones. Ziil attempted to coerce the Skywalkers into joining the sect, and refused to let them leave, in order to protect the sect's secrecy. The Skywalkers resisted, and turned many of the Hidden Ones against him. With the tension mounting between them, Ziil eventually confronted Luke in a duel, which Ziil lost. Ben then revealed the lies which Ziil had told to his sect, and the Hidden Ones revolted against his rule and returned to the surface.
