The Novrosk spaceship was an alien spacecraft that crashed near the village of Novrosk.
History
After the crash, the entire crew of the ship died, and the ship was buried beneath the ground by shifting earth. However, the automatic repair systems and the distress call corrupted the minds of some local villagers, making to strive to gain immortality and repair the ship. The spaceship used Spaceship Remotes to help gather energy, although they had the unfortunate side effect of killing people they drained energy from. The stone circle on a hill near Novrosk was actually the ships antenna, absorbing light energy and sending the distress signal through time and space, where it was picked up by the Doctor's TARDIS, setting events in motion.
