Glory Everlasting

I live on a planet of nobles, knights, and serfs, a new world filled with chivalry, untamed beasts, and hidden magic. We spar with swords, die for our lord and land, and never question our king. But now, because of this Zraian invasion, I'm afraid our ways of old may become extinct. There's panic everywhere, and rumor has it these creatures are out to create a new base on our sepulchers. We cannot stand up to this army centuries advanced, highly trained, and one sighted ... But the world will fall if we don't do something.
