Spread your wings. (Fan Fiction Contest)

So I already entered a submission. I liked it, so I'm not trying to replace it with this one or anything. This isn't a submission to the contest, but rather a small thing I wrote up because I was bored and felt like writing. So, read it, tell me what you think. Hopefully you'll like it. The Buried City. A forgotten metropolis, once one of the shining jewels of the Red Planet. But that was before the Great Catastrophe. While many escaped the death trap that city became, many more died, and their bones can still be found under the dunes. For years the city was abandoned, only to be taken by foreign invaders: The Cabal. Violent nomads with no respect for the people that once called this place home. They patrol the city, looking for added riches and intruders. The Buried City is dead. And its secrets, under the Cabal’s eye, won’t see the light of day. But not for long. The Guardians of the City have flung themselves into the stars, intent on reclaiming humanity’s lost bastions. Outfitted with the best technology and training the City has to offer, humanity’s best and brightest are now no longer on the defensive. They have stopped hiding, they have stepped out from under the Traveler’s shadow. And they are ready to take back what’s theirs. One of their first targets: The Buried City. Treasure hunters and fame seekers from across the City take off in their ships and streak across space to Earth’s nearest neighbor. It’s been a long time since Man’s touched down on the Martian surface. But though we once owned this place, a lot of time has passed since then. Mars belonged to the Cabal now. And they weren’t giving it up without a fight. The Buried City was one of the last places on Mars where the Cabal ruled without question. But due to exploration efforts by brave Guardians, their secret was out. The forgotten city was forgotten no longer. And now Humanity, who had been evicted from their glittering spires so long ago, had come back to take what was rightfully theirs. And at the front of the spearhead were the the brave souls known as the Guardians. The Cabal know they can’t keep Man out for long. This was Man’s home, this was a place he built with his bare hands. And it was his destiny to take it back.
