Definition: In this task, five ordered key facts are given. All the given facts are expressed in natural language. Your job is to generate a story 100 to 1000 words long, that includes all the facts given as input in their order of appearance while expanding upon them to produce a broader, yet coherent, narrative.
Input: Fact1: lands sends out invasion force, Fact2: Black Nebulan fleet wipes out Earth 's space fleets, Fact3: Yamato finds grand white galaxy similar to Milky Way, Fact4: Scaldart appears to be human, Fact5: video screen up on scans surface of planet Yamato

The Black Nebula Empire, last seen in Yamato: The New Voyage, lands a huge fortress on Earth and sends out an invasion force, with the Black Nebulan fleet wipes out Earths space fleets. The fortress contains a bomb capable of destroying half the planet. The Nebulans threaten to use it if they are attacked. The Yamato reaches the other side of the Black Nebula and finds a grand, white galaxy, similar to the Milky Way. They follow a beacon signal to a planet that looks just like Earth. They land, and are greeted by an apparently human woman, Sada, and two officers from the Black Nebulan Empire. They meet the Emperor, Scaldart, who also appears to be a human. He tells them that they are actually back in the Milky Way, in the year 2402. The vortex was a hole in time. The Earth has been under Black Nebulan rule for 200 years, and he is the puppet governor. Scaldart shows Kodai and the landing party all sorts of collections of Earths famous artwork, and, up on the Yamato, the video screen scans the surface of the planet to find all of Earths famous landmarks. Scaldart shows them a time viewing machine which shows the history of the Yamato from 2199 up until the present. Then he shows them the future. The Yamato, orbitting the Earth, is destroyed by the enemys flagship, the Grodaze, in 2402. The landing crew returns, demoralized, to the Yamato... except for Sasha who seems to know her true destiny. She abandons the party and remains on conquered Earth. while alone on the surface, her mother Starsha appears in a vision. She tells Sasha that she was born between Iscandar and Earth, and that her destiny is to die far from both, in service of both. Sasha manages to survive the incineration of the surface by escaping to the planets lower levels. She finds a control center and sends a message to the Yamato, telling them that to destroy Dezarium, they must travel to the core through a huge conduit she is about to open. Scaldart announces after her message that if the Yamato proceeds any further, he will detonate the hyperon bomb on Earth. The blast sets off an explosive chain reaction. The Yamato does a 180degree turn and rushes out of the internal chamber, going to emergency warp when it reaches the conduit exit. Dezarium explodes behind them, destroying the delicate gravitational balance between the two sides of the Double Galaxy. They crash into each other, commencing the birth of a new galaxy.
