Game description from the publisher:

Knowledge is both powerful and deadly in Words of Power, the second Asylum Pack from the upcoming "Revelations" cycle for Call of Cthulhu: The Card Game.

Filled with eldritch Tomes, hidden Libraries, and the Relic Hunters determined to uncover their secrets, Words of Power heightens the different factions' quests for knowledge. While Independent agents offer their services to different groups, the Order of the Silver Twilight works in harmony to plunder the wealth of ancient journals. Research assistants at Miskatonic University delve unwittingly into danger as their study of powerful artifacts leads them across shadowy strangers, Cultists, Servitors, and monstrous black dogs.

The sixty cards in Words of Power (three copies each of twenty new cards) will promote exciting, new synergies with the Relics from the "Ancient Relics" cycle as well as with the musty, old cards lying dormant in your collection. Dark secrets in dusty tomes will determine the fate of the world. Who will find these Words of Power?
