Players use Knights to play the game. All players will be given a free, basic Knight when they create an account, but those Knights are not NFTs yet.
Knights which are NFTs, either won in a Knight Auction, bought from the marketplace, rented from other holders, or newly minted, can earn RUBY rewards when they win a Ranked Game. The higher Level a Knight, the more RUBY they earn.
A player can own multiple Knights, all with different Levels and using different items. Tournaments will have multiple classes so that all Knights can fight with someone their own size.
