Ursini colony is a planet in a distant galaxy.
At one time this planet was discovered by the Ursini, and they began to colonize it, and built a colony on the surface. Some time later, a group of Ursini left the planet, after berzerker drones 'awoke', with the objective of finding a way to stop the drones. After the group found a seed ship, a Control Ship found the colony and wiped out the Ursini with drones.
In 2009 Ursini teams on board the seed ship learned that the colony was destroyed by a Berzerker Control Ship, which probably wiped out the entire population and left the planet uninhabited.(SGU: "Deliverance")
"Ursine" (from the Latin 'ursa') refers to things of or connected to bears.
