Twilight (the Second) is a Princess on the royal court of the Celestial Kingdom. She was born to Twilight Velvet the First, which is the leader of a great and proud unicorn house, together with her Lord husband Night Light. Her brother Shining Armor is the rightful heir to their keep (due to him being the firstborn) and got to marry Cadence, a beauty from the north. Before her parents were able to wed Twilight to a rich Prince or Lord, Celestia found out about her astonishing magical abilities during a tourney. The tourneys in Equestria include magical sports for very skilled unicorns. Since then she’s been living in the grand, shiny, white castle of the great Sun-Queen herself, bathing in her acknowledgement. The Queen had declared her a princess after she successfully protected the kingdom thrice from foreign threats, using her magic and her brain only. Celestia also declared Twilight to her successor, because she’s infertile and thus not able to make children of her own heirs to the throne, but Twilight is like a daughter to her anyways. 

(Alicorns are not immortal in this AU)

Rainbow Dash on the other hand has been a simple squire for a long time. Her house isn’t that big or proud, so she was sent away to become a squire for some knight. What she didn’t know back then, was how much she was going to learn from the person she was going to serve. The knight became her biggest hero, and when the Queen finally knighted her, she knew exactly what she wanted: to become an honorable, loyal knight to the kingdom, always daring and never afraid to wield her sword. That’s why Rainbow immediately joined the “Celestial Flight Guard”, a special royal force protecting the Queen, which only accepts the swiftest pegasi-knights.

So far on their personal stories, but…

…what both of them didn’t plan was an affair. 

Princess Twilight went back and forth with the Queen about whom she should marry, the kingdom needed a bigger royal family and new heirs after Twilight. The decision has almost been made, when Twilight suddenly finds herself blushing over a … knight? A thin, young knight, that has scarcely entered adulthood, with a wild temper and  not a scar on her fur from fighting. Rainbow was ordered to guard her tower day and night, and it didn’t take long for the Princess to notice the flustered looks she gave her every time she entered or left her room.

“I’m a princess”, Twilight thought, “and I get what I desire.” So once Twilight had taken Rainbow inside her room, their little affair had begun.

And until now no-one has found out about their dangerous secret. If it ever came to light that a Princess was having a relationship with a lower knight, that had sworn to not waste his time with foolish love, but protecting his Queen, the outcome would be scandalous. 

Twilight would loose her appreciation on the royal court and who knows what Celestia might think of her…

Well, and Rainbow would probably loose her head.

I managed to write something for my Middle Ages AU, yay! I actually wrote this story before I drew the pic, so it’s just a quick doodle. Very busy times right now so unfortunately not much time for drawing.  

But I hope you like it!
