Xirrith was originally a slave on the planet Polis Magna. He worked as a medical assitant for Tazzim, a private Akonian doctor. When Tazzim died at the ripe old age of 403, Xirrith returned to the slave colonies on Orba Magna, his homeworld. There he was purchased by a Sirrushian merchant's daughter named Dayana Therrick, the daughter of a powerful mine owner back in Sirrush. Dayana was sympathetic to Xirrith, and upon purchasing him, gave him his freedom.
Freedom is not a happy state for a Spheroid, as they are still very robot-like and find it difficult to take full responsibility over every aspect of their lives. As such his slavemaster, Diaphamus, refused to believe he was free. Spheroids are very lawful creatures, however. He knew he was free and refused to believe Diaphamus' lies.
This ultimately led to Xirrith fleeing Orba Magna in a shuttle, with Diaphamus in hot persuit. Both shuttles crash landed on Necra Magna, and both survived impact. Xirrith escaped into the wasteland of Necra Magna, while Diaphamus succumbed to the Deathsteel sickness on the planet, and degenerated into a mindless undead.
Xirrith found refuge with a scouting party of Shadowmongers, the leader of whom was named Voro. After Voro saved his life from a horde of undead, Xirrith believes that Voro is his master, and follows him constantly. Also with the Shadowmongers is a rogue Tokia named Jihahli, and an Immune tribesperson named Elleroh.
