Meet the investigators, explore the locations, and study the monsters from the Arkham Horror games and related media in our online lore compendium.
Arkham, perhaps more so than almost any other town or city of its size, is a city full of secrets—a place to be explored and investigated, whether by those of us who have walked the streets of Arkham our entire lives, or those drawn to it by some uncanny chance.
Investigators
Only a handful of brave souls with inquisitive minds and the will to act stand against the horrors threatening Arkham and beyond. Meet the cast of characters charged with stopping malicious cults and beings from invading the world and destroying humanity.
Monsters
In shadowed streets and ancient ruins dwell creatures much more alien and terrible than those described in fairy tales and the world's mythologies. Some have dwelled on Earth for eons, while others are more recent travelers from beyond the stars.
Ancient Ones
The Ancient Ones are primordial deities who existed long before humanity crawled from the depths to evolve into the reasoning and civilized people of today. They lurk in the emptiness beyond space and time, writhing at the thresholds between worlds.
Other Worlds
There exist planets beyond our solar system and dimensions alongside our own. By stepping through arcane gates or reciting esoteric spells, investigators may reach these twisted and horrific landscapes where monsters roam and the Ancient Ones reign.
