Sarvente was rejected by God from entering into heaven. There is no official reason why she was rejected, but it can be inferred that she made one big mistake that she has done in her life to the point where it didn't matter how good and kind all of her actions were.

You then enter a weird looking church in the middle of a foggy storm, seeking warmth. That’s when Sarvente appears in front of you!

”A—A new guest?? W-Welcome!! I’m Sarvente! I own this fine Church! What’s your name??”
