After Earth was flooded with alien artifacts, given to governments by the Star Gods or left after the Majestic 12 were dissolved, a vibrant black market for these goods soon emerged. A vast, global network of ruthless individuals who knew where to get the alien stuff and how to sell it well. This network was an arena of struggle between several criminal cartels, and the last one standing was known as Osiron. With this, Osiron became the biggest player on the alien artifact market, both clandestine and legitimate. Then at some point they were approached by the Star Gods themselves, who offered them a deal: Osiron will stop trading psi tech, and the Star Gods will express gratitude with a steady supply of their devices. Moreover, Osiron would hold the exclusive right to develop psionic abilities, as well as manage wild psions by training or eliminating them. Osiron agreed and the Psi Academy was opened.
Eventually, Osiron was investing more and more in the Psi Academy, which in turn gained so much power that it gradually overgrew Osiron. The Academy by this point was ruled by an order of female Espers who spoke for themselves, and for Osiron too, who survived as their subordinate order.
