Nopony knows King Sombra's past, the vows he made, the promises he broke. We know that he turned to dark magic, but not why.

This is my take on his story.

Luna finally was allowed to go to school as well as her older sister what kind of troubles will they have to overcome maybe even some romance.

Before King Sombra enslaved the ponies of the Crystal Empire; before Nightmare Moon attempted to block out the sun forever; there were only Luna and Sombra. In a time when Equestria’s peace after Discord’s defeat is shaken, and when alicorns once again come under attack, two unlikely ponies come together beneath the pale moonlight. In the darkness their love blossoms, but so does an ethereal evil that bides its time, waiting to strike before the dawn.

A pony called Harmony Spark has revived King Sombra from the dead and she attempts to befriend and possibly reform him. But Harmony finds out that there is more to him than meets the eye.. She fears something... Or someone, is controlling him. So, Harmony Is willing to help the stallion to enlightenment. But maybe, just maybe, she might get a feeling she never had before...

"Sombra?"
"What?"
"I'm pregnant."
"...What."

Pinkie decides to prank Sombra on April Fools just to poke some fun at him, but her plan backfires when his reaction isn't what she thought it'd be.
