Planet 1865-Alpha was the Borg designation for an uninhabited planet in the Delta Quadrant that had at least two moons and an area of swamp. In 2368, a Borg sphere crashed on the planet's surface. Two of Nine, Three of Nine, Four of Nine, and Seven of Nine were the only survivors. Severed from the Borg Collective, the individual personalities of four drones began to re-surface. Three of the drones attempted to escape the Collective, destroying the beacon they were using to signal the Borg. The Star Trek Encyclopedia (4th ed., vol. 2, p. 148) classified 1865-Alpha as a Class M planet.
