Roughly 20 years ago, Planet Xula;
A woman and a child were seen trudging toward the only entrance of the city surrounded by a high steel wall, mounted by thousands of energy cannons.
The guards deployed outside looked even scarier with every one of them bald with strange tattoos displayed on their foreheads, advanced weapons in their hands, alongside armed vehicles on the side.
Strangely, despite being the only entrance of the city that spans over 65 sq. km, there was absolutely no one going in or out; well, atleast for the moment.
As the exhausted woman and the child reached the entrance, they were suddenly pointed by atleast a dozen handheld energy cannons, scaring the hell out of her.
"I… I… I… have come from the town of Xrusha. Ever since our town was razed by the demons, we were been on the run. We traveled more than a thousand kilometers to reach this safe haven for Terrans.
