Four rival books, each a separate translation of a single source that is long since lost to time. All begin with the same phrase: "Take me and hide me, for I am the one true light". Every journey begins with a choice and the time has come for you to make yours.

Rival Books of Aster is a strategy card game that features over 140 hand illustrated spells that you can use to build custom decks and go head to head against other players. Each spell is also a page in a living story book that translates itself and reveals its secrets as you play the game.

Rival Books of Aster does NOT contain randomized booster packs. Play for free with a starter deck of your choice, and expand your collection with DLC packs containing known-quantities of cards.

Can you decipher the Rival Books to save your household and rule the plane of Aster?
