Las espinas de una rosa infernal... by Camira20

Summary
Adam no reconoce quién le devuelve la mirada en el espejo: el elegante vestido, su cuerpo transformado en suaves curvas, y su rostro, antes masculino, se delinea en bordes dulces.
Sus garras rasgan la tela, sus ojos brillan en algo triste y a la vez aterrador. Los recuerdos de cada demonio, Pecado y noble que insultó su presencia, que despreció quién era, que insinuó a Lilith en su cara. Todos van a inclinarse ante él. -

Summary
"Charlie I.." Lucifer hesitated, phone still next to his ear, he was currently curled up in the corner between the wall and the sofa, a perfect fit, stareing at the ground as he thought about what to say, world spining, kinda fuzzy feelin.
"I don't know I-.. I know how this might sound like but I-" he hesitated, swallowed hard. " I don't really want to talk right now. It's just- it's not you.. it's just not a good time I'm not- I'm not feeling too good sweetie.."

Summary
It's almost Christmas, the most wonderful time of the year... at least until Adam receives a shocking call from someone he'd rather never see, revealing an extraordinary secret and asking for his help to save Christmas. Thus, Adam finds himself caught up in a truly absurd situation, one he's forced to drag Charlie into, since she seems to be the only one who can truly help him and Lucifer. The goal? Transform the whole Pentagram City into Santa Claus's town, and above all, ensure no demons try to eat the children. All this while the unlikely members of this crazy team must do their best not to go mad, which is no easy feat. And also to refrain from beating up those responsible for this mess.
This is the unofficial sequel to the story "How the legend of Santa Claus was really born". If you haven't read it, don't worry; the gist will be explained. However, I recommend reading the other one first, especially since it's very good and just a one-shot, so not even too long to read.

Summary
High School 📚 X Christmas Special AU ❄️
This is a classic high school love story. High school kids fall in love. They mess it up. They grow up.
Yes, let’s make them young. Two teenagers, still learning to exist, emotionally immature, terrible at communicating, somehow making everything worse. They don’t talk when they should, always choosing pride over honesty.
Lucifer Morningstar is loud, defensive, performing perfection for a world never satisfied. Alastor Hartfelt is composed, charming, quietly guarded, hiding behind old-fashioned manners and a voice that makes people listen. Their rivalry starts petty, escalates personal, and slowly turns into a love neither knows how to handle.
They are reckless, dramatic, hurting each other without meaning to, ruining moments that could have changed everything — because they can’t say what they feel.
But fate is already pulling strings. Set against winter nights, Christmas lights, and radio static, this story follows two boys growing close, growing apart, leaving too many things unsaid.

Summary
Alastor may not like Lucifer, but drugging him was never part of the plan—until Lilith forced his hand. The pills don’t strip Lucifer of his essence, nor do they harm him in any way. But they do leave a new person in their wake: a confident, calm, and composed King of Hell. Unburdened by fear, doubt, and struggle, this version of Lucifer is everything he could’ve been. But how would the others react to this new Lucifer? A Devil unchained from his demons, stepping into the unknown?

But he has another meeting this morning, and a wedding to attend in the evening. OH! he can't forget about attending the Goetia's trial tomorrow morning!

Summary
Charlie was not the first being created by mixing a human soul with another.
The product of a Demon Lord and a Sinner. An unprecedented creation that carried the potential to harness untold power in a world where only strength and influence mattered. Lust was a powerful tool that could influence anyone regardless of rank, and being able to use that skill paved the way for a future of success and comfort.
Then the exterminations began. The Queen left, Lucifer delegated his roles to the other Sins, and those gifts and talents became a threat to anyone vying to take advantage of this shift in power.
Pentagram City was worlds away from an early grave, and the Entertainment District Overlords were eager to add someone with such unique abilities to their growing workforce.
Manipulation and mayhem ensue in the battle to regain that once-lost glory in an unfamiliar city where everyone has a desire to be exploited.
What happens when Valentino’s ‘star’ Angel Dust mentions a hotel that offers protection and something better than this new hellish existence?

Summary
He was raised to kill a king. Trained in silence. Forged in shadows. His mission was clear, until the man he was meant to destroy became the one person he couldn’t bring himself to hurt.
Now, caught between a duty he cannot refuse and a love he never meant to find, Alastor walks a blade’s edge. War brews on the horizon, Heaven watches from above, and deep beneath it all, the strings of an unseen master still tug at his soul.
In a hotel built on hope and haunted by secrets, one wrong step could tip Hell into ruin. And this time, love might not be strong enough to save them.

Summary
Octavia Goetia grew up with a reputation for breaking the mold in all the wrong ways, but while her differences isolated her from her peers, that same rule-breaking nature would help her form an unlikely bond with a human. One that would hold strong years later when fate brings them together again, even after she’s grown jaded and replaced her luster for vantablack.
Though since cutting Stolas out of her life, working with her family to take his throne, blooming a friendship with a young band, she begins to fit into the very molds she once broke. Turning her back on the one friend she had when she had no one. But when she learns he’s died and ended up in Hell, she begins to question where her loyalties should lie.
Feeling it's her responsibility to save him and right countless wrongs, she abandons the throne and jumps ship. Hoping to help end the growing conflicts between Heaven and Hell before its too late. But the reality of the situation is worse than she could’ve ever imagined. If Octavia hopes to ever find peace, to save and protect her friends and family, she’ll need to confront what waits in the mirror, decide what she wants and what she’s willing to do to get it.Series
