You are an amateur dracologist in the world of Wyrmspan, a place where dragons of all shapes, sizes, and colors roam the skies. Excavate a hidden labyrinth you recently unearthed on your land and entice these beautiful creatures to roost in the sanctuary of your caves.

During a game of Wyrmspan, you will build a sanctuary for dragons. Your sanctuary begins with 3 excavated spaces—the leftmost space in your Crimson Cavern, your Golden Grotto, and your Amethyst Abyss. Throughout the game, you will build out these 3 caves from left to right, first excavating each empty space, then playing dragons into these excavated spaces.

Each turn, you will take 1 of 5 actions:

(1) excavate a space.

(2) entice a dragon to come live in an excavated space.

(3) explore your Crimson Cavern.

(4) explore your Golden Grotto.

(5) explore your Amethyst Abyss
