My Little Pony: Forever and Ever

[Slice of life, no alicorns, no lifespan issues, native characters, Earth ponies]

Lilith was an Earth pony living in Pony Mafia. Her parents were ponies who worked in archaeology, so by all rights she should have had a place of her own in Pony Mafia. But because of their work, her parents left, and Lilith was sent to Ponyville.

Then a purple pony arrived... and the wheels of fate began to turn.
