Planet: Orelious IX. An ancient species, now extinct and thought to be both inventive and very resourceful when in battle. Several battle strategies which are still used originated from the Menthars (the Kavis Teke elusive maneuver and a passive lure strategem comparable to one of Napoleons'). Their entire race died out over a thousand years earlier because of a devastating war against the Promellians which extinguished both sides, and destroyed the planet.
