Profile
Sector Eridanus, in stark contrast to the other Schwartzwelt Sectors before it, does not resemble any part of human vice or sin; rather, it's the Schwartzwelt's own idea of Earth after the eradication of the human race. Clean gardens, shining white walls and a considerable amount of rare technology all blend together around a huge tower. At the top of that tower there are multiple screens showing past images, moving pillars and a pure white expanse around a clear sky. In spite of Eridanus' beauty, it also contains the first instances of poison and sleep traps and has a huge area devoted to teleporter riddles and trap holes spanning two levels.

The first mission posted by Arthur is to find the Vanishing Point, the Schwartzwelt's single exit point; he explains Eridanus is in a different point in space-time, and that if the crew kept following the trail marked by the Rosettas they would merely return to Sector Antlia. While exploring, the crew find an offline teleporter; when activated, they find a demon guarding another teleporter, insisting his master had posted him there. Not too long after, the MC also finds a rare forma allowing Irving at the lab to improve his Forma Search function.

The crew is initially elated to find Eridanus, by all indications, is the last Sector, and that after they leave the Schwartzwelt Joint Project will firebomb the entire dimension, presumably eradicating it, with nuclear bombs.

Soon after this, Arthur notices disturbances that point to another ship in Sector Carina; the crew are ordered to pull out of Eridanus and investigate. Jimenez and the Protagonist investigate and find a vehicle resembling the ones they used to enter the Schwartzwelt and hail them, believing them to be the Gigantic; however, Arthur realizes it's in fact the Lightning-the initial prototype of the same vehicle type, sold to a private foundation. However, he also notes its systems, especially weaponry, have been heavily augmented.

Making contact, the crew of the Lightning introduce themselves as Jack's Squad, a mercenary unit sent to the Schwartzwelt in a search for valuables. Their leader, Captain Jack, proposes an impromptu non-aggression pact in exchange for three rare forma his team cannot locate and the superior Forma Search program. The protagonist agrees with Arthur's consent and returns to Eridanus to find the missing Forma. Once they return, the demon in the teleporter lets them pass and gives access to Eridanus' full map.

Once the protagonist returns to Jack with the forma, the pact is sealed and they agree to part on neutral terms with the agreement to help each other in case of need. With Eridanus fully unlocked, they find the way to the upper levels and to Ouroboros, the Demon Leader of Eridanus. However, he's unable to unlock the doorway to Ouroboros and the Vanishing Point until he completes Jack's request; once this is done, a Squad member gives him a superior Gate Search program and leaves to capture several demons.

At Eridanus' top floor, the Protagonist also notes his Demonica has data indicating he had been there before- which he thought was impossible. However, upon reaching that area, he finds the Norns and an inert Yggdrasil, who reveal they used to be the Disir he volunteered to help on Sector Bootes. With their powers replenished by Yggdrasil's pacification, they send the Protagonist to defeat Yggdrasil in the past thorugh their timetravelling powers to save his past self from being killed at its hands. Once this is done, he returns to the initial point and leaves, again rewarded for his bravery.

Once reaching the Vanishing Point, Ouroboros attacks; he's, however, undefeatable, as killing him only revives him on a stronger incarnation, and the Protagonist is forced to leave. Jack, between the Protagonist and Arthur's discussion, interrupts to point out several dots funneling energy to Ouroboros. Once the demons at those points were killed, Ouroboros' endless energy is depleted and he's vulnerable again.

Defeated, Ouroboros loses a small energy band which the MC pockets. With the Vanishing Point open, the Red Sprite prepares to leave- except The Three Wise Men interrupt their exit with a potent energy blast and knock them off course, making the ship careen and lose control until its crash on Sector Fornax.
