Asteroid Theta 12

Asteroid Theta 12, also called Asteroid Theta, (AUDIO: The Neverwhen) was an asteroid which was used as a base by a faction of Dalek Scientists who secretly plotted to restore Kaled mutants to their humanoid form during the Last Great Time War behind the Dalek High Command's back. Eventually, their secret was soon found out. The Dalek Fleet ordered the experiments to be cancelled, but the Scientists refused declaring a conflict. The asteroid was severely devastated in the attack. (AUDIO: A Thing of Guile)
