Immortal Armada

"He's been planning his return. His followers have been building something for years. The largest fleet the multiverse has ever known. He calls it the Immortal Armada. In twenty-four hours, attacks on all free worlds begin. The Dark Emperor and his fleet have been hiding in the Unknown Regions on a world called Exegol."

--Poe Dameron

The Immortal Armada was a massive fleet of unmanned Star Destroyers/Dreadnoughts secretly constructed by the exiled remnants of the Empire of Darkness led by Dark Emperor Torvivum Zuskelgar on Exegol. Alongside an army of Sith troopers, the Immortal Armada was the culmination of an agenda over a thousand years and a conspiracy decades in the making. With the Deathshead; a Xyston II-class Star Destroyer armed with an upgraded axial superlaser capable of destroying entire worlds, acting as the fleet's flagship, the Immortal Armada's ultimate objective was to bring the multiverse under the perpetual reign of a new Dark Empire through military force.

As the Grand Alliance fought against the Coalition of the Red Star, what remained of the Dark Empire, are labored to create the largest armada in universal history. The Immortal Armada's existence was revealed to Supreme Leader Victor Nevarez by Zuskelgar, who urged the Dark Lord of the Sith to take the fleet and rule all the multiverse as the new Dark Emperor.

Ultimately, the Battle for the Multiverse was a decisive defeat for Torvivum and his followers, with the Immortal Armada utterly destroyed by the Alliance and the Free Worlds Fleet, As a result, the Coalition was openly attacked by an uprising of people on numerous worlds across the multiverse.

"The might of the Immortal Armada will soon be ready. It will be yours if you do as I ask: Kill the boy, end the Jedi, and become what I have once before. You will rule all the multiverse as the new Dark Emperor. But beware: He is not who you think he is."
