"And I saw, as it were, a sea of glass mingled with fire and them that ... stand on the sea of glass. ... " Revelation 15:2 KJV
The whole planet was covered in water except for the towering spires of the double city. Some thought it two cities, though in actual fact, the city was one long cylindrical structure that jutted out at both ends of the planet’s equator. The molten planet core was the regenerating power source of the impaled planet’s citizens.
Connecting the sister populations of the one structure were roads of transparent light that circled the globe. One band of light circled from north to south. One band of light bound the city from east to west. Each band of light penetrated each city as it transported the inhabitants of the plains of moving glass. It was these that had broken away from the city itself as the water and its peaceful light-displays beckoned the city dwellers.
At times when the inhabitants started their journeys along the corridors of light, some remembered when roads were made of sand-colored earth with towering iron structures that towered and curved inward down the roads of a different world. Only in their minds could they revert back in time and try to recall the exact order of the structures and their meanings. This knowledge came not consciously but when the mind was at peace and contemplating the endless roads of light and the cities of pure water and foam that graced the endless world. The ancient dwellers had called this world, Marcontinuo, or ContinuousSea. Though in that distant time, there were no roads of light, only of the simple, but agreeable earth that dirtied one’s feet, but became more endearing as one tried to wash it off and a glint of light lit up one’s feet through the night. Such was the wonder of that ancient yellow earth.
Many thought it was this natural element that had preserved the races of the planet through centuries of changes and natural upheavals in the seas and in the skies. The wise men said, however, that when the Rulers of Light arrived with their gift of the glowing roads, the yellow earth would not be useful and would need to be pushed gently into the sea to find, perhaps, another world and civilization to sustain and delight with its perplexing qualities of shimmering night phosphorescence.
