Every night, Princess Luna soars through the land of dreams, shepherding the minds of her subjects. It is lonely, thankless work, forgotten by the ponies she helps as soon as the sun rises.

And sometimes she comes back with them.
An homage to Luna and little siblings everywhere. Keep up the good fight.

Luna feels that being immersed brings a pony closer to her world. And Celestia doesn’t understand.
Some lessons require special measures. Along with a lot of water.
And tiles. There’s definitely going to be tiles.

Sun & Moon Act I: Ascending Star by cursedchords [86k words]
https://www.fimfiction.net/
This is Sun & Moon, the story of the two alicorns around whom Equestria's history is indelibly wrapped. And this is its first chapter, a story of the search for hope in darkness, and the lengths a pony would go in order to find it.
Equestria's history is a multicoloured and complex tapestry, speckled with the works of the great ponies of its past. But there is one dominant colour, visible everywhere, and that is the contribution of the two ponies who saw it all: Celestia and Luna.
A comprehensive understanding of Equestria is impossible without first knowing their whole story: from its start, in the middle of Discord's Chaos, to its finish.
Celestia and Luna were born into a lawless world, just two alicorns trying desperately to survive. Little did they know the great destiny that fate had chosen for them. On the road to that destiny, they will discover everything that lay underneath the Equestria of old, and set the stage for all that came after.
