From the twisted growth on the outskirts of Arkham to the darkened angles in the very corners of withered homes lies a vast menagerie of evil waiting to be summoned!
With Fate of the Elder Gods: Beasts From Beyond, your cult will use new spells to make some of the most classic creatures from Lovecraftian lore do your bidding. Your cult will have a chance to bring forth the mysterious Mi-Go, the Dark Young, Deep Ones, Byakhees, Goat Spawn, Hunting Horror, a Hound of Tindalos, or even the terrifying, but unpredictable Shoggoth. Players will also get a chance to summon four new Elder Gods: Shub-Niggurath, Ghatanothoa, Dagon, and Yig.

About Cult Cards, Azathoth, and the Promotional Monsters
[...] Just like Azathoth, we also recommend that you do not include Cult Cards or the Beasts From Beyond expansion in your first games of Fate of the Elder Gods. There are plenty of awesome things to do and explore in just the base game. Once you all know the ropes, you’ll be ready to tackle the extra challenges!
