A mystery Library in hells king and queen palace

DISCLAMIER- This Lucifer that is mentioned has nothing to do with the from hazbin hotel, religion, or hellvaboss. Lucifer is my Oc's husband, and this is a random moment in their relationship!

One day Nova was strolling around in the palace until she came across a door she could have sworn she had never seen. Nova has walked every part of the palace and been in every room. So, her curiosity got the best of her and Nova opened up the door and lied a huge library. When Nova was looking around, she saw ancient hell relics that looked like it was from the heavens. And books with shimmering gold lining. It was huge Nova had been to a library before but not a library this big filled with objects. There were even Hellish and Heavenley like armor lining the windows. The chandlers' bulbs were beautiful as they gleamed among the ceiling. As Nova was looking at all of the different kinds of books, she couldn't have wonder of what the books were containing inside. Some contained secrets about heaven others about secrets in hell. Nova wondered why this place was hidden or if she was in a dream of some sort. But one thing caught her eye and it was the windows some looked beautiful, and you can see from the outside but a few windows like a prophecy. But then Nova realized why the library was hidden it's because of what it contained. If the sinners got their hands on the relics the books full of secrets. Then possible doom could have been upon hell or heaven. But Nova didn't care if doom came upon heaven not going to lie. But Nova chose to look around even more to see what the library contained. But while Nova was looking around and reading some of the books Lucifer came inside the library. "NOVA WHY ARE YOU IN HERE YOU" Lucifer shouted. Nova startled Nova went on and explained everything she found and saw. Nova asked why he was hiding all this from her mean they have been married for 2 years Nova would expected Lucifer to her everything. But sept the library contained so many powerful relics and so many secrets that means there could always be a possibility sinners/demons could steal it. Because they have had thieves come in and almost steal their items, but Lucifer and Nova know how to deal with people like to steal from them. Lucifer did apologize to Nova about shouting at her though because he feels like he shouts at her for no reason sometimes. But Nova does yell at Lucifer over the dumbest reasons as well. Obviously, Nova forgives him because she knows he didn't mean it. So, Lucifer chose to tell her all the backstories of some of the ancient items and relics. Nova does nothing but listens to him with a huge smile and also admires him and the item or relic. As he explains the story's he realizes that Nova is more likely just getting distracted by him and his stories. Even Nova's wedding ring had a backstory the ruby is from the deepest caves of hell. Some ancient items and relics even confused Nova though. But Lucifer was willing to tell the story if it was a hurtful story he didn't want to be reminded of. (I am going to change it up a bit even though it has nothing to do with the prompt) As a few hours past Lucifer got bored and decided to take Nova's hand and take her to an empty space in the library and asked for a dance and Nova agreed. They sung they danced underneath the star diamond chandler. They enjoyed time together for hours and they couldn't wait for more adventures together. Even though they were in hell Nova and Lucifer weren't going to let that ruin their time together. Lucifer grabbed a crown that was sitting on a shelf and placed it on top of Nova's head. Her crown was an upgrade from her previous one her crown was black with pure red ruby's. Lucifer showed Nova some of the books and relics that he didn't show previously. But Nova saw one that she wanted to place on top of his head, but Lucifer stopped her. Nova asked why he was stopping her from grabbing it. But there was no response only dead silence from Lucifer. The item was Lucifers fallen halo still intact. Nova felt bad for grabbing it and trying to put it on his head. "You will always be my angel Lucifer no matter if you like it or not" Nova said with her head down while looking outside the libraries window. Lucifer smiled and gave her a kiss on the lips and thanked her for that complement. As the couple sat in the library admiring the beauty they were wondering what some of these books had in store. Lucifer may have created the library but that doesn't mean he knows every last bit of the books. So, they explored the books a bit some were more interesting than others they had nothing else better to do anyways. "You know being in love with you is like a fairytale" Lucifer said with a happily as he looked through the books that held mysteries. "Lucifer you do realize some fairytale love isn't real sadly" Nova pointed out. "Hey, you're the story of my life" Lucifer said as he smiled at Nova. Nova was delighted and felt special after Lucifer said that to her every now and then she felt like there love was fake but little comments like that made her doubt that thought. But she wondered if there were any spell books that can help her with her dark magic. And the library did not disappoint it had it all the shelf she found had it all of what she was looking for. Lucifer was also finding some things in the library that entertained him as well he looked around. As they were looking around putting things back for the day though they felt like they had an adventurous day even though it all took place in 1 room. It still made them happy for spending time together. (Yeah, I understand this was kinda nothing to do with the prompt but hey it included someone finding a secret library also sorry about the title)
