Synopsis
The Vorlons have started openly destroying worlds which have come under the influence of the Shadows. Wishing to move against them, Captain Sheridan sets in motion a plan to remove the Vorlon ambassador from Babylon 5.
On Centauri Prime, it is revealed that the Shadow vessels stationed there have made the world a target for the Vorlon advance. Londo Mollari urges Emperor Cartagia to remove the Shadow's ships, and is refused. It transpires that the insane Cartagia expects to ascend to godhood (Apotheosis) when the Vorlons destroy his world.
Lyta Alexander lures Ambassador Ulkesh into a trap. The Vorlon's encounter suit is destroyed, and the Vorlon, revealed as a tentacled being, is defeated by Sheridan, Lorien and a remnant of Ambassador Kosh. Sheridan is rendered unconscious during the battle, and is revived by Lorien. It is revealed that Sheridan only has another two decades to live.
