Since you first woke up in a dank and gloomy tidal cavern, you've tried to pull together the disparate pieces of your shipwrecked memories. You've learned pieces of why you came to Innsmouth, and you've fought the evils rising from the ocean deeps… but as you escape from the Deep Ones overrunning Innsmouth and race toward the Falcon Point lighthouse, you find yourself at the gateway of the next mystery. Who was it that first caught you and left you for dead? The keeper of the lighthouse might hide the answers you seek.

As the next part of your evolving story, A Light in the Fog expands your adventures in Innsmouth with Arkham Horror: The Card Game, picking up where your frantic car race left off at the end of Horror in High Gear, and promising new revelations as you dig deeper into the heart of the tangled conspiracy that surrounds Innsmouth. Along with a new scenario, this expansion, the fourth Mythos Pack in The Innsmouth Conspiracy cycle, offers new options to your decks with a slew of new mid-level cards to shape and improve your deck as you gain experience. But as your experiences unlock new skills, will they open a door to deeper shades of madness?
