In the world of Durania, their was a war between Humanity and monsters. Humanity composing of multiple intelligent humanoid races, and the monsters consisting of powerful creatures. this battle waged on for thousands of years. until, a mage which was a cross between a human and a monster, smashed the world into 4 pieces with the forbidden spell, Ragnarok. now, Aero, brother of the leader of Xenotech, a company which works on rockets to investigate space, is sent out to investigate the chunks of space, and he crash lands, trapping him on that world. this is my first story. please give me fair criticism.
