What is the name of Dark Souls’ first major expansion?

Dark Souls’ first major expansion is Artorias of the Abyss. It adds a story campaign set in the past, new areas, bosses, weapons, armor, and characters connected to the Abyss and the legendary knight Artorias.

The content was first released with the Windows version’s Prepare to Die Edition in 2012. It was later included in the console release of the Prepare to Die Edition and in Dark Souls: Remastered, so modern players may encounter it as part of a larger package rather than as a separate purchase.

The expansion is accessed through a quest involving a portal and the character Dusk of Oolacile. Its setting, Oolacile, expands the game’s history and provides context for events and figures mentioned in the main adventure.

It is often confused with downloadable content from later Souls games. The Old Hunters belongs to Bloodborne, while Ashes of Ariandel belongs to Dark Souls III and Crown of the Sunken King belongs to Dark Souls II.
