You take the role of a downtrodden swordsman of a nearly extinct race known as the birdmen. Years of training and battle leave you unfulfilled and without purpose, so one day, you leave home to discover the fate of your lost childhood love. Your quest for perspective is abruptly cut short when you are shot from the sky by a group of human warriors who specialize in trapping birdmen for use as slaves.
You wake up with your wings clipped and sword confiscated, in a land ruled by a sadistic king who posesses a strange obsession with harvesting the mysterious "red seeds". You come to realize that the fate of the one you've been searching for is intertwined with the king's nefarious ambitions. In order to meet her again, you must get your hands on a sword, escape enslavement, and carve a path of blood to the ominous Spire City.
