second invasion

my platoon was re-deployed on blaho a very rural planet. we mainly lived in the interior of the planet which appeared to be an old pontari structure. and it contained several terminals which told the stories of this ancient race. our latest innovations were inspired by their artifacts and tech. soon an invading raltiont fleet came. "All civilians please evacuate to the nearby shuttles" boomed a radio. our team ran dow the main shaft with taipu. he was fast with his new armor. when we knew we were safe we saw interesting lantern like object out of instinct i pulled on the object thinking it was obviously a very important terminal. "crack, rumble, boom" the planet groaned as metal pieces of a massive ring the encircled the planet broke into smaller bits and floated to a stand by position above ground. a door opened before us and taipu said, "let's go!" we ran and soon reached a whole that had the grooves for the key. i placed it in and the entire mass of dirt that made up the planet shattered and and a tube (obviously a cannon) came out of the sphere. suddenly a control panel popped up and like clock work the ultra carrier appeared "fire the cannon taipu!" i shouted. he pressed the button and the broken halo began to spin. faster, faster, faster it span. then the loudest blast i have ever heard and it shook the gun like a tree branch in autumn i saw the carrier. it had many small explosions erupting around it and in the end the most spectacular explosion i ever saw blasted like a volcano and i actually was literally blinded and shortly afterward i had to get specialized eye therapy to see again. the cannon itself merely collapsed due to its age. blahs was no more.
