The universe is like a large complex spiderweb, with each separate pony its own point, connected to the other ponies by the web's various strands. And, like a spiderweb, take one pony out, and the universe becomes a mangled version of what it used to be.

This is the story of a young filly who managed to erase herself and her connections from the universe, from the circumstances that led to her disappearance, to the consequences of her actions.
