New World, Equestria

The new world consists of Artemis city (Crystal Empire), Solaris city (Manehattan), Avian City (Cloudsdale) and Elysium (the new capital). Each city is built for certain tasks. Artemis city is built for mining the resource that powers everything, Solaris city is the primary city for manufacturing of machinery and weaponry, Avian City makes the weather work depending on the situation (big surprise) and Elysium is the capital that runs the new world. It is easily the most advanced with its size easily being that of a small province. It is a metropolis at its core. Towers stretch into the sky for what seem like miles. It is also the most protected to the point of near isolation. Walls surround the city with guards holding off the entrances. If anyone dares try to enter without permission, they get killed.

A desolate landscape of what was the old capital of Equestria. The remains of which are now in shambles and abandon. The remains of those who perished in the great wipeout sit on the city's edge. Their remains a reminder of the city's demise. Those who stayed. The mares, stallions, fillies and colts. They live in the abandoned city as a reminder of what was. A broken reminder of what was once a utopian society. Now lay to rest as the castle falls apart piece by piece. The plants slowly taking back what was once their land.

It was nearly five decades since the return of the Crystal Empire. Ponies were still using magic at this point in time to say the least. That was until one day while in the Empire's mines. Deep down into the caves sat a source like no other. A crystallized liquid that glowed red when touched. It was eventually discovered that this substance was double the power of the Prince's as well as discord. It was an odd find at first due to how the Crystal Heart accepted it. It definitely was more powerful than any magic ever seen. Almost as soon as it was found, ponies wasted no time in mining this powerful resource. New technology came out. Ships that could cross the country in a matter of a few hours, weapons that overpowered anything they used before, artificial intelligence and so much more. Ponies could even be injected with it to make them stronger and able to perform most tasks other wouldn't. This didn't mean that it didn't have opposition. Ponies that still used magic hated the new substance and how it tried to kill magic. Some groups even tried sabotaging operations and what not. This didn't stop production until it completely stopped suddenly. Ponies weren't allowed near any mines containing it, ships that had it were confiscated by an anonymous company, only a select number of ponies were injected and finally the empire went under siege. After a few years, something finally did come up. Cities were being wiped out one by one and assimilated into submission. First the empire, then Manehattan, Fillydelphia and so much more. Magic users were given a choice to either give up their magic or be killed. This caused a mass exodus to Canterlot which went under siege like the empire. Only they kept themselves shielded with magic until they felt safe. This didn't stop them...
