The Eternal Slumber is the special event quest for Gen Con 2018, and will also be made available in Invocation Kits this fall, before Arkham Nights 2018. It is a one to four player scenario which can be played as a standalone scenario or integrated into any Arkham Horror: The Card Game campaign as a side story. FFG will be recording the results of every playthrough of The Eternal Slumber at Gen Con 2018, and the player's choices and performance during the scenario will have lasting repercussions for the entire Arkham Horror: The Card Game community at Arkham Nights. This is included in Arkham Horror: The Card Game – Guardians of the Abyss: Scenario Pack. —user summary
