Humanity explored the Lasron solar region, colonised Auros and constructed the Lodestar Station 479 on Hurala. Hurala was a frontier staging world, used as a stop off point for people on their way to other planets, including Klechton, Jalian 17, Tenten 10, Blenhorm Ogin and most notably, Arkheon. However, due to the escalating conflict between the Dalek and Earth Empires, the planet was abandoned.
In the 26th century, during the Second Dalek War, the Daleks attacked Auros. The human colonists surrendered. They destroyed the planet using Osterhagen technology rather than have it fall to the Daleks.
The Tenth Doctor arrived on the abandoned Hurala via a time slip in his TARDIS. He became trapped on the planet but rescued by the crew of the Wayfarer after several days. Later, the Doctor defeated the Daleks by destroying part of the planet, taking the Lodestar station and the Daleks with it. (PROSE: Prisoner of the Daleks)
