The Lunar Kingdom

In an alternate universe where Luna discussed her jealousy with her older sister, Celestia and Luna came to a compromise. Equestria would still have day and night as normal, but Luna got her own section of Equestria where those who prefer the night can live.

But the dreams of everypony in Equestria must still be taken care of. Luna began asking for volunteers in the Lunar Kingdom to help watch over the dreams of ponies.

It's not an easy job. Rainbow Dash knows this. She's been trying to work up to the higher ranks, but finds herself falling short time and time again. When she meets her favorite Wonderbolt in a dream, he offers to help her improve her abilities.

They find themselves falling for each other, though the only time they meet is through other's dreams.
