“And this?” the young man pointed at the shining, rainbow-like cover enveloping Titanium.

“It’s the outer energy field generated by the nucleus and functions as passive protection from a possible attack from the outside.”

“How could people have created such a thing and launched it into space afterwards?”

“The planet was built in space. At the base of the building process is a constantly perfected nanotechnology. The tiny nanites process raw materials and recreate the necessary construction elements according to the project.”

“Did nanites build all this?”

“Yes, nanites and the robotic devices. The raw material was the debris of a gigantic asteroid field. Our scientists have found a way to convert the basic chemical materials from the asteroids into the chemical combinations necessary for the construction. Titanium prevailed among other solids that were used; hence the name of the city: Titanium. Travelling in the megapolis is possible by means of a teleport. I think it’s time you had a real feel of the transport system at work. There are also stairs, but they’re not as popular. The teleport system is the fastest transport means in the spaceship.”

“The fastest after the stairs?” smiled the young man.

“No, after the micro-transport on the electromagnetic pillows,” Grinning, Lora pointed at the guest’s chair. Suddenly her tension that had been so strong back in the ward was melting away fast.

“Do many people use them?” asked Derek, feeling genuinely curious.

“Not these ones in particular, however, there are many devices for carrying different loads. By the way, the central teleport is a public transport, but there are also freight units.”

“I get it, like buses and lorries.”

“Buses?”

“Well, it’s like some old-fashioned transport means with tyres. They used to travel by land burning tonnes of petrol. However, they were improved later when the electric engines were introduced.”

“They̓re described in encyclopaedias,” Lora tried to remember.

“They must be.”

“So, you remember the transport means on Earth. Anything else?” asked the girl as they were slowly heading towards the closest teleport.

“I remembered when you started talking… This information sounded like something I take for granted…”

“The doctor said that you would remember things which were associatively connected to your memories.” remembered Lora.

“Looks like he was right then.”

“I can take you directly to your apartment if you wish to rest.”

“I’d prefer to take a walk if possible,” answered the young man.

“Alright, what would you like to see first?..” At that moment the UCD on Lora’s temple buzzed softly, lighting a green colour which was indicating an incoming call. “Will you excuse me, I’ll have to take it,” she explained to the man. “Yes, Jean.”

After a short conversation she returned to the previous discussion with the guest from Earth.

“I was going to show you some of the local attractions…”

“What’s that?”

“This?” the girl touched the mini contraption with her palm. “It’s a universal communication device, UCD for short.”

“Is it a walkie-talkie?”

Lora frowned trying to remember the meaning of this word and finally answered.

“It connects people, but that’s only one of its functions.”

“Why didn’t I hear the voice of the other speaker?”

“A UCD transforms sound into an electrical pulse and transmits it onto the auditory nerve.”

“What else can this device do?”

“It provides a connection to the central computer, thanks to which any information that I may need reaches the brain through the visual nerve and visualizes as if in front of my very eyes. Again, only I can see those images.”
