Each player’s progress towards winning the game is tracked by the number of keys they have forged. The first player to forge all three of their keys immediately wins the game.
Each player has one key of each color: red, blue, and yellow. Some card abilities may reference the color of your keys, including which of your keys are forged or unforged.
If an effect introduces addtional keys to the game, any additional keys are colorless and can only be forged after all your other keys have been forged.
For details on forging keys, see “Step 1: Forge a Key”
