Fifth Planet Gambit

The Fifth Planet Gambit  was a name later given to the Time Lord expedition that intended to break Planet 5 from its time loop and utilise the Fendahl against the Enemy. (PROSE: The Taking of Planet 5, Pre-narrative Briefings)

Unbeknownst to the Time Lords, the expedition was manipulated by the hermit so that the Fendahl Predator could be released and set on the Celestis. (PROSE: The Taking of Planet 5)

While this mission indirectly caused the destruction of Mictlan, therefore removing the Celestis' influence from the War in Heaven, (PROSE: The Taking of Planet 5, The Book of the War) the Fifth Planet Gambit was ultimately designated a failure on the Homeworld. Afterwards, Xenaria was regarded as a war hero and given the honorary title "Xenaria Who Survived". (PROSE: Pre-narrative Briefings)
