Everyone in school had that one classmate who was involved in all sorts of shady businesses.
This person could do anything if given the right price and spent most of his time outside the class rather than inside.
Elias was one such person who Sebastian knew back at the academy, as despite the strict security system in the school that made stealing things from the various laboratories impossible, Elias still managed to sneak out high quality potions, unique artefacts and invaluable books.
Sebastian had paid the guy once for some health potions, and it was in that brief conversation that the two had that Elias revealed that his family was in the planet acquisition business.
It was a very shady business they ran where they were contracted by various corporations who needed migrant workers to forcefully heckle and vacate the immigrants of a planet and force them to become migrant workers for that particular corporation.
