Dark Souls Remastered is a remastered version of the first game in FromSoftware's Dark Souls series, it also marks the first appearance of any games from the series on a Nintendo platform. The remastered version also comes with the DLC, "Arotias of the Abyss", in the base game.
The world was once shrouded by grey fog and ruled by dragons. In this time period, Gwyn happens upon the First Flame and finds a Lord Soul. He and his allies use their power to defeat the dragons, beginning the Age of Fire. Over time, the flames begin to fade with the rise of humans, and Gwyn sacrifices himself and his soul to prolong the Age of Fire. With the flame artificially rekindled, the undead curse begins to plague humanity, causing certain humans to continually resurrect upon death.
At some point, a being known as Manus began to spread darkness in the form of the "Abyss" upon the land of Oolacile, the knight known as Artorias was sent to stop him but failed and was corrupted by Manus' influence. Manus then search for his pendant lost across time and space.
The player is one of those cursed undead and must fufil Gwyn's prophecy and keep the flame alive but after a fight against Gwyn himself, the player is left the choice of actually prolonging the Age of Flame or let the flame die out and let the Age of Dark takes place.
The player eventually find Manus' pendant and is then pulled into the past where he must fight against the corrupted Artorias and Manus himself. After his defeat, the land of Oolacile is freed from the Abyss.
Dark Souls Remastered retains the minimalistic story telling of the original version and most informations about the world is learned by talking to NPCs and reading items' descriptions
