Crucible

The Crucible was a planet-sized space station that served as the Daleks' headquarters. The Daleks planned to detonate a reality bomb onboard that would destroy the BZPB Multiverse, but were defeated.

History
The Crucible became the center of the Daleks' operations at some point in the ancient history of the Original Universe. The Daleks constructed a reality bomb aboard that they intended to detonate and destroy the BZPB Multiverse once the right conditions had been met. When Blackout discovered the threat that the Daleks posed to the multiverse as a whole, he gathered an army that also included Artrix, BoM Master, Findor, Kakamu, Malygos, TMV, and Zev Raregroove, among others, and declared war on the Daleks. A Dalek saucer then abducted Findor, so the allies chased it all the way to the Crucible, but most of the army was then destroyed by a single cannon blast and the survivors were captured and brought aboard the station. Blackout and Zev were both brainwashed by the Dalek Supreme and forced to attack their allies, but were freed when Malygos teleported to the main control room, deactivated the Dalek Supreme, and activated the Crucible's self-destruct function. All non-Dalek survivors were then teleported to safety before the Crucible was destroyed.

In 150,080 CMT, Blackout, Overlord Blackout, Ynot, and Hollow Ynot were sucked into a crack in time that transported them back in time to the Crucible. Blackout realized that they had arrived in the middle of the reality bomb crisis, so Ynot decided that he would hide himself and do nothing in order to avoid interfering with the time stream (because he had not been present when the reality bomb crisis occurred). However, the Daleks detected Ynot's presence and trapped him in a force field. This made Ynot decide that he had had enough temporal shenanigans, so he used a Memory Seal to transport himself, Blackout, OB, and HY back to their own time.
