A registration plays, explaining the place is a sort of processing network called Eden Log, whose workers are all immigrants promised citizenship in the society above ground.

The stranger, in great pain and sounding deranged, tells the man he's the creator of that entire system, and then warns him about an unseen menace.

As a result, the corporate overlords ordered the security forces to forcibly take control of the network levels and seal the area.

A figure in a protective suit uses a bright light and loud noise to scare the mutants away, then knocks the man out and restrains it, fearing he's infected as well.

The figure, being one of Eden Log's botanists, explains the goal of the entire structure is to generate power from the sap of the living plant at the center of the network.

The two are now on an elevator, and during their ascension, the man is suddenly overwhelmed by a sexual urge, that quickly degenerates to the point that he brutally rapes the botanist.

The botanist sees white cubes with human workers inside, and realizes that's where the infected are stored, not to be cured but to be exploited for energy themselves: the dangerous "secret" the corporate woman from the registrations had alluded to.

He sneaks into a surveillance room and begins watching the videos and piecing all the information together, finally rediscovering his own identity: his name is Tolbiac and is the commander of the security force tasked to quell the rebellion.

On the surface, Tolbiac is saluted by Eden Log's corporate people for protecting the company's secrets as he stands in front of an animated board depicting the full process of the power harvesting procedure: the immigrant workers are purposely sent to the lowest levels, given sap to energize them, then work until they are depleted or dead as their energy is harvested to power the city above; this is society's way to "integrate" the immigrant populations.

The surrealistic landscapes of Eden Log were inspired by Vestiel's favorite films, such as Escape from New York and Dawn of the Dead, and comics and literature, such as Frank Miller's Daredevil and Métal Hurlant.

They noted that Eden Log appears to have been influenced by role-playing games and the works of Luc Besson, Marc Caro, Jean-Pierre Jeunet, and Darren Aronofsky, as well as channeling the "rich visual history of French comics, or bandes dessinées, from magazines like Métal Hurlant and its American counterpart, Heavy Metal".
