From the smallest detail down to every piece of technology there, the man would find that the part of the 'city' he was in would be exactly as how he would remember it, preserved to the exact state it was in when the Suvian had died (disappeared, what?)
Though the rest of the city-planet had been advanced and evolved to unimaginable feats, this part of the city had been left untouched, labeled 'The Ruins of the Suvian' in respect for the original owners, and kept in its perfect, though truthfully unperfect condition that it had held when the planet was first re-discovered.
Only wanting to improve upon and the city, and tasked with caring for it, Rev and Gen had left the old city ruins alone in respect and merely built 'atop' it the many layers of Lus. Because of that, this was the lowest part of the planet one could get to, it was the very 'core of the core' and the final layer of the planet only known to the higher AI and the kids.
Above the ruins, would be the core that was known to all AI, higher and lower, and was somewhat of a way station for them. And above that, the control rooms of the entire planet, where Rev, Gen, and their guest Relle were currently at with AMI.
Further above that room would be the inner city and and built above that layer was the outer city. There were no real differences between the inner city and the outer city as both were equal. It's just some wanted to live further in protection, where some liked to be closer to the stars.
Around the entire city was an outer shell, which served as the 'atmosphere' of the planet. To the people inside the planet, it was transparent and they would be able to see the night sky, as well as the false day sky. To the people outside it, they would see only a metal encasing made of a strange material, that could project images onto its surface like that of a giant television screen.
The man would find that if he wanted to get anywhere on this planet now, he would have a long walk, a long, long walk as the ruins were very deep down.
