The Horror

The Horror was an amalgamation of beings which had been abandoned in the Time Vortex. When the Time Lords sent Chris Cwej into the bottle universe, they unintentionally created a gap through which the merged entity invaded the bottle universe's operating system. (PROSE: Dead Romance)

Some of the beings that were part of the Horror were:
 * Pool (PROSE: Deceit)
 * Salamander (TV: The Enemy of the World)
 * Ruath (PROSE: Goth Opera)
