In the new world of Grelatin. Where the era of Humanity still used iron and stones, Kingdoms are non-existent, the skies are dominated by Elder Drakes, the lands are conquered by Behemoths, and the seas are ruled by Ancient Whale Sharks, came a man from another world in an unknown craft.  He who came from another world was expecting Dinosaurs and a lovely tropical scene. Though he is welcomed by a dragon. And explosions.
