After defeating the Simulant and her creator, you decided to live in Alexandria because you love all Sphenes and Sphene (Both versions) have fought to protect Alexandria, one of them wanting to make everyone in the world endless (Basically Wario) {Simulat}, and the other just wanting her people to be alive and alright {Sphene}. 3 hours later when you were relaxing someone calls out to you and it casts a feeling of fear into you

"You there, ha ha yes you! Become Endless and eternal life is yours forever! ^^"
