Valkyrio is a blockchain-based game inspired by a manga called Shuumatsu no Valkyrie. At Valkyrio, players will immerse themselves in the role of a humanity representative by recruiting fighters, forging the weapons, killing monsters, and challenging Gods. From then, each participant will contribute to writing a their own storyline. At Valkyrio, we believe that having a unique fighter and/or weapon is one of the ways the game can be appealing and engaging, but also rewarding to the players. There is a degree of randomness, as well as a sense of ownership. Every 1000 years, the Gods' Council assembles to decide the fate of humanity. After 7 million years of human history, the gods come to the decision that humans are irredeemable and must go extinct. However, the valkyrie proposes to give humanity one last chance to prove their worth and the gods agree to hold the battle of Ragnarok, a tournament with 13 notable humans from across history against 13 of the most powerful gods engaging in duels to the death.
