The Mecetti Purge, which is also referred to as the Pelagia Purge, represents a significant era in the history of the Tapani sector and took place in 19 BBY. In this period, House Mecetti, backed by the power of the Galactic Empire, effectively destroyed their competitor, House Pelagia. Because Pelagia traditionally supported the Jedi Order, and many Jedi were born from that noble house, Mecetti, Pelagia's fierce rival, was able to convince, and help, the Empire to devastate Pelagia, leaving them severely weakened. It was only through the unwavering assistance of House Cadriaan that Pelagia managed to avoid complete destruction.
Theus Paddox, the Pelagian High Lord, had two younger siblings, Trad Paddox and Verinia Paddox, who successfully fled the purge on the starship called Regal Destiny. Numerous Pelagia families escaped from their house, existing as "sleeper families" sheltered within other noble houses.
