There are twelve of us, four from each tribe. Twelve of the most elite and powerful guards in all of Equestrian history with one goal in mind: to protect Princess Celestia’s life no matter the cost. Error is not a word in our dictionary. We don’t comprehend the definition of failure.

Honestly, it’s not all that bad. Sure it’s tight out there - but we’re family. A close, knuckleheaded family of brothers and sisters bonded through putting up with Celestia’s nonsense. There’s not a thing we wouldn’t do for each other. The Princess knows it - it’s why she trusts us as much as she does. And why we trust the Princess as much as we do.

*EDIT* Holy smokes. Featured? This is probably the best day of my life since ever. Wow.

Many thanks to ward282, MagicKnight55 and metallusionsismagic for proof-reading and editing. I wouldn't have made it this far without them.

And also, many thanks to Cormac McCloppy for help with the earlier chapters. I wouldn't be here without him

In the magical land of Equestria, two alicorn sisters raise the Sun and the Moon every day to give the world a night and day cycle, basic for the survival of life. There are also two alicorns who rule over two very core aspects of life and harmony itself. Those are Love and Friendship. While not as ancient as the two sisters, all princesses are essential to the world's balance.
This balance is also sustained by the hard-working ponies, who make the seasons change and manage the weather to fit their needs, so everypony has enough food and water, and every animal is also attended to assure that any of them are caught in the changes of seasons.

But what about the planet itself? What about Mother Nature?
This is the question that Gaia asks when she arrives to this foreign world. After so much work her son persuaded her to take a long vacation in Equestria, saying that she needed one and assuring her that he would be in charge now, and she must take a break. But what can a several billion-year old alicorn possibly do to pass her time in this land?
