"Our forces are only a small part of a larger empire known as Etronia, and my brother and I serve as the leaders of one of their five military branches. This is by no means our first planet, or even our first universe that we've inhabited, mind you."
She places a small device on the table, that shows a hologram of the earth. "Obviously, our initial battle in New York ended... unexpectedly, but that aside, our plans are somewhat simple. One by one, we intend to completely upgrade and rework the major cities of the world into entirely self-sustaining, surrounded by barriers and walls. Each of these is capable of functioning on its own, and comfortably containing dozens of times more humans than the current level of technology this planet has access to. From there, we'll work our way down to smaller cities and towns, and eventually connect them all through elaborate highway and teleportation systems."
The hologram switches to show a series of massive domes, each lined with high-tech walls at their base, and advanced-looking cities inside. the buildings stretch higher than any skyscraper on earth, and the design as a whole seems quite cyberpunk and vertical. Each of the domes has multiple tunnels, supported by large pillars, leading out of it that act as highways. It's also worth noting that much of the metal making up these structures is a dark purple, almost black.
"Residential areas, Agriculture, Industry, et cetera. All of them will be contained within these cities. As for the land outside, it will be purified of toxins and pollution, returned to its natural state, allowing the fauna and flora of this planet to flourish without human interference. Two perfect worlds existing on the same planet."
