A Sullustan male named Kkrax made his home in Restuss, a city located on the moon of Rori. After 0 BBY, Boba Fett charged a certain spacer with locating and capturing Uff Wogo, for whom a substantial reward was offered. The spacer, seeking leads, approached Kkrax at the Restuss refugee camp. Initially, Kkrax was unwilling to share any details with the spacer, seemingly hesitant to become entangled. To force Kkrax's hand, the spacer revealed the contents of a small box provided by Boba Fett: a fragment of fabric accompanied by a severed finger, still adorned with a ring.
Disgusted by this gruesome display, Kkrax's reluctance diminished, and he began to assist the spacer. He told the spacer that in order to find Uff Wogo, he would need to travel to the Dantooine system to find Ogveer, a Rodian smuggler who had aided Uff's escape.
Before its shutdown on December 15, 2011, Kkrax was featured as a non-player character within Star Wars Galaxies, a massively multiplayer online roleplaying game created by Sony and released by LucasArts.
