Lodestone and Granite accidentally stumble upon a tribe of warrior humans with rudimentary runic magic in the Everfree Forest. Ancient spirits of the forest task them with caring for the humans and giving them a better life. Princess Twilight, Rainbow Dash, Fluttershy, and a host of other ponies all join in to help these two with this monumental task. Granite and Lodestone, naturally, wind up becoming very close friends, and several humans form relationships with these new ponies as they slowly introduce them to modern civilization.

This story is over 400k words long. It was originally an RP between myself and two other writers: AWF, and Metsu. Apologies for any weirdness because of that, though I have been editing it as I post to try and minimize that.
