Raiders of the universes

"Raiders of the Universes" by Donald Wandrei is a science fiction novella written in the early 20th century. Set in the 34th century, it explores the discovery of multiple new stars in the constellation Hercules, leading to a catastrophic invasion from a dark star that threatens the solar system. Central to the story is Phobar, an astronomer who grapples with the unimaginable forces at play in the universe. The narrative follows Phobar as he witnesses the birth of new worlds due to cosmic phenomena and the terrifying approach of an alien planet, Xlarbti, which is driven by a ruthless civilization that seeks to extract Earth’s radium. After being transported to Xlarbti, Phobar learns about the invaders' advanced technology and their disregard for life on Earth. As the tensions rise and the fate of humanity hangs in the balance, Phobar manages to outsmart the colossal rulers of Xlarbti, leading to the repulsion of their impending doom. Ultimately, the novella combines themes of scientific curiosity, the fragility of human civilization, and the ethical questions surrounding power and piracy in the cosmos.
