Cyvasse, the game was called. It had come to the Planky Town on a trading galley from Volantis, and the orphans had spread it up and down the Greenblood. The Dornish court was mad for it. Ser Arys just found it maddening.”
— A Feast for Crows, George R R Martin
This board game has been developed from fan-made rules and the few mentions it gets in the Song of Ice and Fire books. Each symbol has been hand-drawn then laser engraved into each piece. The board and all the pieces have then been hand-finished and waxed for protection.
