Warhammer: Newly Forged Battleship, Building an Empire!

After transmigrating into Warhammer, being nonhuman might just be a blessing. Akivili, who had become a battleship, was very satisfied with his species. He didn't have to fight and die for that half-dead Corpse Emperor, nor fear the four gods of the Warp playing with his soul. From [Torpedo Boat] to [Gloriana-class Battleship]; From [Men of Iron Remnant] to [Humanity's Second Home]; From [Imperial Traitor] to [Humanity's Sanctuary]; As more and more people moved aboard this battleship, as it grew from a few kilometers to over a thousand kilometers, eventually becoming larger than a star system and housing a population of over a trillion, as more and more people defected from the Imperium of Man to the Battleship Empire, even Primarchs leading their Legions to forsake their father's love and move to this beacon of hope for humanity... The Necrons chose to join, and the Orks chose to move in too. The beautiful ecological domes were lush with greenery, the banquet halls piled high with cakes, and people drank and made merry. A battered battleship drifting through the universe would eventually become the final [Noah's Ark] in this doomed, chaotic world, bearing humanity and all living things to safety.
