1948. The first thing Lunimere heard after dying was the wind. Opening her eyes, she looked around herself, and then at herself, but she was surprised to see that she could barely see her own body. And she was floating, above the mansion that had taken her life. Starfield was missing... but somehow, Lunimere knew that he had made it, to a place she hadn't. But why hadn't she? Was it Polaris?
It had to be. Figuring out how to fly was difficult, but Lunimere wouldn't be the first ghost to figure it out. Finding Polaris wasn't easy, though. Their house was abandoned and empty, she obviously couldn't just ask somepony, and both her car and his limousine were missing. Thankfully, she spotted the armored car, her own car, and a trailer parked at the place they were going to build their radio company. Phasing into the trailer, Lunimere's heart broke, or it wouild have, if she had one anymore. She had only ever seen tears come from Polaris during their wedding, and a few really sad movies. But the way he was crying now made her wish she could hug him, more than anything else. But... she couldn't. Not for lack of trying, but for lack of a body.
And that made her mad. She was still here! Why couldn't she help him!? Lunimere didn't get an answer, of course, but from then on, she followed Polaris. As he built the complex, she stayed at his side the entire time, watching over him. When Celestia met him to ask about the bunker, she was happy to see him say yes, since she knew he liked the idea of bunkers. She watched him drown himself in his work, then in the stallions who were hired to help. Now, that was a side of him she hadn't seen before.
1972. The project money for his bunker had run out, but Lunimere was happy to see that Celestia was going to pay him for the bunker maintinence, since it was intact and could hold all of Ponyville in emergencies. Now, she hadn't really expected him and his new friends to band together to build and launch a nightclub, but... well... it was entertaining to watch, at least.
1986. She was excited! Polaris' music albums had taken off, and Lunimere almost vibrated with excitement as she watched him dress up in a shiny latex suit, ready to pull off a concert in Ponyville. Time seemed to fly as he sold out increasingly large concerts, until she floated along in his car with him to Manehattan, for a big concert in 1987. She was worried about the song, though... it was a song he had written about her, and he had yet to fully sing it by himself without breaking down. She watched from the rafters during his performance, and she shared his pain as he began to falter during the end. The ride home was hard to sit through, but Lunimere didn't dare leave him.
1992. Jeez, Polaris, took you long enough to find another marefriend! Lunimere wasn't sure about this new mare, but they seemed to mesh somewhat well. Circuit getting pregnant was a bit worrying, but Lunimere was along for the ride, and while she didn't like seeing them break up in 2004, she was glad that Polaris handled it well. Changing the name to PolariSoft was an interesting change, but she was glad to see that he kept the old logo in a few places.
2005. As time went on, Lunimere learned about computers alongside Polaris, and she watched as he began to code an AI that would eventually become Saphira. She was so happy when the digital mare first began to talk to him, since while he loved the daughter he had with Circuit, the little girl did live with her mom, not him.
Now, 2012 was wild. That was the year Polaris discovered the Underworld, and experiencing the awe he did during his trips around the underwground nation was one of Lunimere's most fun times as a ghost. Well, except for Limestone town. There were OTHER GHOSTS in that town! And not even THEY could talk to her! It was cool that his dad was not only alive, but ruling as a king down there.
The rest of the 2010s was a blur. Polaris found that not only was his dad alive, but his mom too! He turned one of his airplanes into a pony, so now he had three daughters. His mom moved in, Reeve moved in, he found Tenticla underneath the bunker, then he turned a TANK into another pony, so he had a son now, she guessed. The AI mare was pretty advanced by now, and they even gave her a body!
With his life becoming more of a routine, time seemed to speed up even more, and it seemed like it wasn't any time at all that Polaris was getting into spacecraft technology. Lunimere was rather proud that Polaris and Saphira became the leading ponies when it came to making Spaceship software and computers! She even followed him into space one time, which was an odd experience, since she could float right out of the spaceship if she wanted.
And then, everything became a mess as Equestria began to fall apart. Suddenly, Polaris was all over the place again, and the monotony of the life he had settled into was shattered. For both her and him, it was like their lives had sped up and slowed down at the same time.
Soaring into space on the SS Twilight with him was incredible, and Lunimere couldn't wait to experince his new life with him. But things had gone pear-shaped, hadn't they? Shadow was a terrifying force to both Polaris and herself, because Lunimere could feel the mare's strong magic pulling at her whenever she floated close.
But she had just taken Polaris inside of her. Polaris, the stallion she loved and followed, no matter where he went. Lunimere hesitated for a good, long while, but she flew towards the giant mare, and she shuddered as she hit the magic, which resisted her for a brief moment before she sank into it. She cried out silently as she was absorbed by the whirling mess of magic, and she felt herself fading away into its chaotic power.
