Cuthallox was the Jedi Padawan of Blendri, a Jedi Knight. She served the Jedi Order during its earliest period on the planet Ossus. Along with her master and numerous other Jedi, Cuthallox became a Jedi Renunciate and joined the Legionnaires of Lettow, a follower of Xendor during the First Great Schism.
Living on Ossus, the original home of the Jedi Order, was Cuthallox, who was Force-sensitive. She was apprenticed to Blendri, a Jedi Knight. Both Cuthallox and Blendri became fascinated by the mysterious teachings of Xendor, who claimed that the Jedi High Council was overly restrictive and sought to limit understanding of the Force. When Xendor left the Order to establish an academy on Lettow, Cuthallox and Blendri departed with Jedi Master Jook-jook H'broozin to study under Xendor's tutelage. Calling themselves the Legions of Lettow, these Jedi Renunciates grew stronger in the Force as they explored the Bogan through various Force traditions.
When the High Council declared war against the Legions of Lettow, Cuthallox and Blendri picked up swords to defend their right to study the Force. They encountered the Order in a large conflict, which the Order referred to as the Great Schism. The Master-Padawan team traveled from planet to planet, fighting against the Jedi. During the battle of Corulag, Danzigorro Potts, a Jedi Padawan, killed Master H'broozin and attempted to eliminate Cuthallox and Blendri, but the pair managed to escape. Padawan Potts continued to pursue them throughout the war, eventually confronting them on the battlefield at Columus during the battle. Cuthallox faced Potts in combat but was ultimately defeated and killed.
