Fifth planet (of twelve) of a single star system in the Orion Quadrant.Gethsemane was wiped out by collision with a rogue planet. Most of the adult population escaped through a massive interdimensional portal they believed would take them to the Afterlife. (It was actually intended by the Kariad to teleport them to a less doomed planet, but it didn't work out that way.) Children could not leave through the portal and thousands were left to die on the planet. The Pathfinder Ship Pegasus was able to rescue most of the children before the planet was destroyed.
