Dark Souls: Artorias of the Abyss is a downloadable content pack for the 2011 action role-playing game Dark Souls.
Artorias of the Abyss is set a hundred years before the events of Dark Souls. The player is taken back into the past by a primeval human known as Manus, Father of the Abyss, who was resurrected and tortured by the sorcerers of Oolacile a century prior, hoping to unlock his dark power. Manus' power went wild and created the Abyss, a dark void that threatens to swallow the entirety of Oolacile. Anor Londo sent Knight Artorias to slay Manus, but he was unable to withstand the dark onslaught due to his lack of Humanity and became possessed himself, only able to save his wolf companion, Sif.
