Ascension is a deck-building game with a fantasy-world theme - monsters from another realm are invading and each player is building a team of heroes and constructs to defend our world. Players spend Runes to acquire more powerful cards for their deck, and use Power to fight the monsters. The goal is to earn the most Honor Points by gaining cards and defeating monsters.
Storm of Souls is a full-size expansion that can be played separately from the original game. It introduces events, trophy monsters, and fanatics to the game.
