Harkyn is the protagonist of Lords of the Fallen. Unlike many other RPG games, the player does not create a custom avatar. Instead, players customize Harkyn by selecting a Magic Type and starting equipment (Warrior, Rogue, Cleric). These two factors dictate what class Harkyn will be. There are nine classes, and each has its own strengths and weaknesses.
In an unforgiving world where no sin is ever forgotten, Harkyn, a convicted criminal, is given a chance for redemption. Just when rulers of the world get close to finding a way to banish all evil from humans, an army of the long-ago defeated god attacks the human realm. Released from prison, Harkyn and his mentor, Kaslo, set out on a mission to stop the war.
