Arkham stands on the brink of destruction as eldritch forces rise from the depths in the stunning conclusion to Arkham Horror's The Drowned City.

Harvey Walters knows the end is coming. Arkham is overwhelmed by flooding, and from the depths strange creatures have arisen, drawn from another dimension by the approach of an ancient being determined to destroy the city. And amongst the chaos, another force seeks to seize the influx of supernatural power for themselves.

Arkham is under siege from all fronts. But Harvey Walters is not going down without a fight.

Teaming up with garbageman, Lefty Googe, and reporter, Minnie Klein, Harvey is determined to save the city he loves from annihilation. His mind and a stolen wand are his only weapons and as Arkham crumbles around him, Harvey must draw on all his mystic alliances to make a last stand. He's gambled with the arcane before, but this time the stakes have never been higher.
