Story
In ages past, five kingdoms ruled the known world. Each kingdom possessed a sacred relic given to the kings of old by the god themselves. The relics guided and protected their armies in battles. As time passed, younger kings desired to gain absolute power of the land and waged countless wars with each other. The gods were displeased with the reckless actions and greed each kingdom took part in, so they took back the relics, hid them in a large tower, and proclaimed: "Whomever is able to pass the challenges of this tower will become the ruler of all known land." Years passed. generations passed. No one, man woman, or child has been able to complete the challenges within the tower. This is the story of one such adventurer, Wing, and his Adventure in the Tower of Flight.
