The Kingdom of Argai came into being around 25,200 BBY when the pirate known as Xer founded it.
Xer declared himself the ruler of the planet Argai, and from that base, he established his own kingdom inside the existing Kingdom of Cron. He seized control of [Dravione], then spent the next ten years growing his kingdom to include [Corlass] and Panna. Initially, the Kingdom of Cron paid little attention to Xer's actions, as they were more concerned with internal political machinations. Nevertheless, Xer's power grew to the point where it could no longer be overlooked. Ferece, the King of Cron, attempted to convince Xer to swear allegiance in exchange for noble titles, but the pirate instead launched an attack on the Kingdom of Cron. He then took the throne, becoming the new king of Cron, and the Kingdom of Argai was once again part of the Kingdom of Cron.
