The High Fane of Xo, situated on the planet Nuswatta, served as the central base of operations for Xo's hierophants, an age-old religious sect known for their practice of sacrificial rituals. During Xer VIII's power grab within the Kingdom of Cron, Xim's forces destroyed it, subsequently transforming the theocracy to serve Xer.
Following Xim's defeat at the Third Battle of Vontor, the Hutt Empire initiated a campaign of genocide against the Tionese people in the Kiirium Reaches around 24,500 BBY. The hierophants, fearing their own demise, abandoned Nuswatta. They sought to establish a new fortress, where they planned to await what they foresaw as the ultimate conflict between Humans and Hutts. This battle, they believed, would herald the end of days and the Perfection of Xo. The Tionese never received any further communication from them.
