These are real monsters in the city, but they never surface for real. Rando and Melanie keep talking to the computer system of the space station, that’s how they programmed it. Lengthy conversations both of them, in the several CPU rooms located city wide, like ATM machines, stinky places, like old talkies. The spirit of the others was a woman, pretty, like a mom, who was very trusty, appealing to Rando. The only reason I guess how he survived the spirit was by giving his love to it, instead of Melanie. She understood, that it was required, that’s also how Melanie proved so useful to Rando, a true soul mate. They only rendezvoused in there, never together, that could awaken the monsters. So if Rando was taking the hit talking staying in love with the spirit, Melanie was able to complete most of the work for Rando, allowing them to move to safer locations within the city. They had to stay in constant transfer from one site to another. In reality the spirit was only wanting a mishap or computer failure, and worse entrapment by monsters. None of that ever happened because Rando had Melanie doing all the work, then rendezvousing with him, thus averting the others. But it was a long way for both of them, and both got ambushed as well several times by the others.
