Hello!

I'm trying to find a specific story featuring Celestia -- It was...I think it was essentially Equestria falling to pieces and Celestia ending it for good so that the world could start anew? I do remember that it involved an altar and her stabbing herself.

If anyone could help me find it it would be much appreciated.

Sounds sort of like Her Blood Ran in Hollows of the Floor?

Sadly not the one -- iirc in the story I'm thinking of there's literally noone else left alive. Still, thanks!
