Play cards by positioning magic sigils on the crescent moon. There's no limit to how many cards you can play, as long as you have the space!

With three playable characters and hundreds of cards to choose from, there are countless possible decks with a variety of strategies and play styles.


Position your sigils strategically and get massive bonuses for adjacency, overlap, and more!


Some sigils persist on your board between turns or have ongoing effects. Certain enemies will even cast their own hostile sigils onto your board!


Upgrade your cards and inscribe them with runes of power. Spread the benefits over your entire deck, or put everything into one or two overpowered cards.


Travel across the fallen realms and experience visions from beyond. Choose between mysterious boons, powerful upgrades, and more.
