Elden Ring 2 proposed story

It focuses on seemingly a sequel set after Age of the Stars. A age filled with fear, doubt and loneliness in the ambience of the Night.

The player is seemingly not the tarnisehd and is called by a voice who hates Ranni and the age of the stars and wants to bring an end to existence.

The voice sounds more and more like ranni as time progresses and she recognises the player as the consort in their past life.

The final boss is Ranni and the Tarnished.

the twist is that this is a false version of the age of the stars brought by a non linear version of Rannis cast off flesh. The age of the stars never happened yet and that wasn't ranni.

The age of the stars is to bring about the beginning of existence, not a improvement of "existence" that is the antiexistence of the Elden Ring.

The player (who is a version of the tarnished) fights the fake tarnished and fake Ranni.

In a non Linearity, Ranni in the night of the black knives slays her flesh. The fake ranni silmultaneously becomes a blackened corpse. Ranni takes the Elden ring out of the blackened corpse and

The game loops back to the exact same age of the stars cutscene from the base game. Ranni eternally departs with the Elden Ring, the tarnished comes along.

Taking away all fear doubt and loneliness, the Night, as existence begins for the first time.

And yes the game reveals itself to be a non linear prequel to the age of the stars ending in the base game.
