Warhammer 40K Noble Family Meets Earth Players

On the dark edge of the Warhammer 40K universe, on an abandoned mining star called "Rust Star", the time traveler Sebastian Van Reinhardt - the "wasteful second son" of the Reinhardt family - accidentally bound to the "Earth Player Summoning System". Faced with his father's mess of embezzling military funds to buy antique power armor, his eldest brother's iron-blooded power grab, his second sister's cult fanaticism, his third brother's rebellion against the Mechanicum, and his cousin's gene-stealer conspiracy, he could only resort to the ultimate weapon: summoning a group of hardcore earth players addicted to "Anoxia" and "City of Exile" to use infrastructure, Excel and square dancing to carve out a strange territory where "the whole family can live together" in this "only war" universe.
