Nothing puts a new perspective on the phrase ‘You need a hobby’ like being over a thousand years old. Celestia and Luna could personally attest to that. Being the immortal demi-goddesses of the Sun and Moon that they were, the fads and fashions that often gripped the mortal ponykind could pass by the sisters’ attention almost completely. As such, both of the sisters had developed their own little hobbies to occupy their attentions, regardless of what ponies thought about them.

Being literally as different as night and day, the two sisters had different interests, and their spare time activities reflected this. Except in one rather peculiar case. Both sisters wrote, their stories based around real-life events. Sometimes it was to get the raging question of ‘What if X happened, instead of Y?’ out of their heads. Sometimes it was to live vicariously through their writings. But mostly, it was to pair up every single pony in as many combinations as possible, regardless of if those combinations made sense or not.

And naturally, this spawned more than one argument between the two sisters. And like most things between the two immortal alicorns, things had a habit of...escalating.

Luna stared at her sister across the great expanse of water. They were out at sea, which made a great deal of sense, especially since the last time the sisters had clashed horn to horn, the resulting outpouring of magic had carved out Horseshoe Bay. Luna shook her head to clear it of those thoughts, and instead adjusted her tri corner hat, and used her magic to direct the ship she was standing on to open fire at Celestia’s.

Luna’s ship was decked out in swathes of purple and white, and the image of Celestia’s cutie mark, crossed with Twilight’s, adorned the sails of the ship.

“Come now, sister, you must admit that Twilight has feelings for you!” bellowed Luna, utilizing the Royal Canterlot Voice for its intended purpose: yelling at the enemy on the field of battle. “It is the most logical!”

“Nonsense!” came Celestia’s reply, along with a cannonball. “She is far more likely to be enamoured with you. She has always loved the stars, and you were always the more magically proficient of the two of us. Twilight could not resist such a thing.” Celestia’s ship was covered with purple and dark blue, and had an image of Twilight’s cutie mark combined with Luna’s on its sails.

“But you were her teacher, sister. The forbidden love between teacher and student!” Luna ducked under another cannonball, and magically commanded her ship to return fire.

“The shared love of studying magic, and the night sky will bring the two of you together, Luna!”

“Twilestia!” Luna’s ship fired, and the cannonball punched a hole in one of Celestia’s sails.

“Twiluna!” Celestia’s retaliating cannonball took out one of the masts on Luna’s ship.

“Teacher-Student forbidden love!” Luna’s cannonball smashed into the side of Celestia’s ship.

“Shared magic appreciation!” Celestia’s shot tore through the rear of Luna’s vessel.

Cadence and Twilight watched from the air, as the two alicorn sisters more or less waged war on each other.

“Does this happen often?” asked Twilight, wincing as Celestia’s ship took a particularly brutal hit.

“You’ll get used to it,” was Cadence’s calm reply.

“That didn’t answer my question.”

“Twilight, if there’s one thing I’ve learned since Princess Luna returned, it’s that sometimes you just need to let things happen. This is one of them.”

Twilight thought back to her attempts at analysing Pinkie Pie, and then nodded her agreement.
