This river stone was a thirteenth birthday present for Obi-Wan Kenobi, given to him by his Master, Qui-Gon Jinn. It was smooth and black in color, and when light shone on it, red veins were revealed in it. Obi-Wan's initial reaction was confusion and disappointment that he had received a gift from his Master that seemed to have no value, but he soon came to appreciate his gift. When Obi-Wan was captured by the Syndicat, a criminal organization that controlled the planet Phindar, he was saved from the terrible fate of being mindwiped by the Sydicat because of the stone's powers. He found that the stone was Force-sensitive, and that he was able to use the stone to wrap his mind in layers of the Force, allowing him to retain all his memories. Later, he asked Qui-Gon whether he had known that the stone was Force-sensitive, but Qui-Gon revealed nothing to him. Obi-Wan later gave the river stone to his own Padawan, Anakin Skywalker, for his thirteenth birthday. Anakin was noted to be more grateful to have it than Obi-Wan had been at first, as he knew it had once belonged to Qui-Gon.
