EDEN Corporation

The eDEN Corporation is a faction in Just Cause 3.

The corporation only appears as a part of the Sky Fortress DLC, Mech Land Assault DLC and the Bavarium Sea Heist DLC, which all expand the backstory and add more information. It would be too complicated to sort the information by individual DLCs, so the article is based on all available information as a whole.

Description
As revealed in the Eden Callaghan tapes, the eDEN Corporation was founded in the 1980s by Eden Callaghan. She was a scientist herself, but she became the CEO of the new corporation.

The purpose of the corporation was to use money from private investors and governments to create research facilities for the development of new technologies.

It's unknown how big the corporation previously was, or what they owned. They didn't become significant until they purchased or rented Insula Lacrima from president Dante in the 1980s. At that point their operation scaled up in every sense. They got more funding, more research bases and more scientists to work for them.

Some of their projects were disasters, causing them to lose all private funding and forcing them to reluctantly co-operate with Di Ravello.

Eventually their AI project killed them all and made a deal with Black Hand. The company's security force is presumably dissolved and the Black Hand pillaged all the research bases at Insula Lacrima (However, there are still abandoned stations that are still heavily guarded by eDEN drones once utilized by the company's security force that were never reprogrammed and thus will attack any intruder on sight, Black Hand included) and sent some guards to the eDEN Airship (The Black Hand doesn't really care if Rico is on the Airship, or not. As long as you don't have Heat, it's fine to hang out with them on the ship. This is possible on the lower side of the Stern Section). When the Stingray base and its surrounding rigs reappeared, the Black Hand also seized control of those.
