The Elysium Sky Ship. Just before the great crash of the Meido Zangetsuha asteroid on Earth, the leaders of the world came together and devised a plan to help salvage at least some of the Earths populations. They created hundreds of these Elysium Sky Ships to escape the fire and dust that would shroud the Earth for years to come. The model of the Butterfly was chosen, in hopes that the world would one day be in peace.
