Sargonian diaspora

• Noted historical event in the spread of humanoid-form intelligent life in the space straddling the Alpha/Beta Quadrant border, including most Federation known space (TOS Novel: Ex Machina; TNG Novel: The Buried Age)
• Following the collapse of the Arret Empire, the two dominant species either regressed and rebuilt civilization on former constituent worlds or spread out across space, seeding development of many modern Human- or Vulcan-form species known in the modern era (TOS Novel: Ex Machina; TNG Novel: The Buried Age)
• All known Vulcanoid species, including Vulcans (and their cousins, the Romulans), Zami Rigelians, and Minkarans, are known to have descended from the Sargonians (TOS Novel: Ex Machina; TNG Novel: The Buried Age)
