An exploded planet, halted in mid-destruction by a time anomaly. The planet contained an unstable, fiery core which exploded after many millennia. The inhabitants were warned by the Time Lord, Shade of its impending destruction. With his help they engineered a device similar to a morph-lock, which would create a time anomaly; suspending the time stream by halting the explosion mid-occurrence and encasing the planet within a bubble of time.
At the great blast, the surface broke into five large, intact land masses called continents, and was flung into space but then held immobile by the time anomaly. Gravity remaining, the continents hang suspended in orbit around its perpetually burning core. Survivors of the catastrophe exist on the surface of the continents, struggling to rebuild their civilizations, though most of the population was destroyed.
