The E.S.O.'s company logo.

The Ein Sof Organization, or E.S.O., is an extremely influential Mars-based corporate conglomerate backing over a third of the Martian government's financial and military needs. Its influence expands well beyond its home planet, with several Earth-based nations also connected to the company through trade agreements. As of recent times, the company has begun showing itself on Earth on a much greater scale, mostly due to its friendly relations with the United Federation in accordance with their alliance to Mars.
