Carrisent Particum

The Carrisent Particum was a small spherical green object, that Narvin likened to a paperweight.

In actuality, when the Fourth Doctor's Time Ring was discovered on Skaro following the genocide of the Dalek race, the Unified Skaroan Alliance, made up of Kaleds, Thals and Daleks, had used the Time Ring to gain access to the Time Vortex. The Alliance had then gone on to conquer Gallifrey and time itself. They had then placed the Warrior on trial for crimes. There, the Warrior and the Master worked together to place this alternate timeline within the Particum, ensuring that the timeline never occurred.

Back in the original timeline, the Warrior explained to Narvin that the Particum resembled Skaro itself. The shifting green surface of the object was Skaro's sky. The Warrior kept hold of the Particum to ensure it never fell into the wrong hands. (AUDIO: Aftershocks)
