Princess Celestia's history with Spike goes back a long way, back before he was even laid. His mother, one of Celestia's oldest and dearest friends, had gifted Spike to her with the hope that he could grow up in a world that loved him.
But Spike hadn't been alone.

These days, the dragoness who mothered Spike is all but a forgotten memory, though the legacy of her brood lives on...
... in the magic of Equestria itself.
