Today’s a cold one, the weather is sombre, and the sky is grey and full of mean looking clouds.
Styx returns to the hideout drenched and grumbly, but some warm food, light banter with you and some snuggling, everything gets a little better.

Summary
Touch, that’s where it all started, a supple touch against his forearm a gentle drag like a blade of grass in the wind caressed by the curls of air currents, his heart stopped for just a moment a feeling he never felt before.
At first, he thought he was poisoned and had finally met his match, but instead, it was something far worse as Styx concluded that...
He was in love.

Summary
Demons have all sorts of ways and forms of presenting their love, whether its through means of utter incomprehensible violence or simply by giving the gift of a lovely sweet flower, either way their jealousy and possessiveness has a chance to shine through even greater than a star, so beware the love of the demon, you're but humbly their sweet morsel for only them to savour.

Summary
Greenskins series is all about my favourite goblin Styx, anything I’ve written with him in it as singular one-shots, fluffs or smuts will be in this series including crossovers of him with other characters such as character x reader x Styx.
Note if you have a prompt idea for Styx but are not sure how to write it out do share! I’d love to write your prompt ideas!
I am also available to co-author if you need help writing Styx.

Summary
Welcome to the SinVerse, my own version inspired by the UnderVerse, except within this realm of mine things are a far more darker and twisted take upon the originals.
With entirely different origins and events that have happened, you’ll truly be in for a lovely twist with all sorts of rich plot and character along with a tasteful slowburn.

Summary
The premise is as old and used as the dirty old rag you’d find squished behind the pipes under the kitchen sink. But it’s been on my mind since I first read “The Soldier and the Carnal Skeletons” by Writers_War_Z0ne and others inspired by their work. It’s occupied me so much, in fact, that I decided I’d like to take a crack at it.
You're the plucky Reader/Protagonist. There's an island. There are skeletons. Shenanigans ensue.

Nightmare never expected to come across someone like you.
He never expected to feel these feelings you've stirred in his SOUL either.
He's determined to make you pay dearly for it.

Summary
You have never felt as pathetic or unneeded as you do now. You look at them from afar, seeing her beautiful figure on his arm as if she belonged there. Grin and bear. Force a mask of happiness for them, even if it hurts and couldn't be farther from your true feelings. ‘Smile. Laugh.’ Try not to think about the fact that he isn’t yours. Don't show how broken you are inside.
A month passes and you hadn't realized until now, that you aren’t the only one who has been affected with this new dilemma. You see him there, miserable and defeated, just like you. For the same reasons. Mirrored broken hearts falling onto one another for comfort only the other can give, because you both know exactly how the other feels.- Language:

Summary
All it took was a crash landing in a part of the nature preserve and state park you lived in and patrolled. Now you find yourself dealing with a rather spoiled and bossy alien ruler that is marooned on Earth. And from what it looks like, he’s not getting out of your hair anytime soon.
*Indefinite hiatus*
*Updates will typically be on a Friday, Saturday or Sunday. I will try to keep it consistent and update at least once every few weeks, all depending on work, other fics/projects and other life things that go on. Thanks for understanding!*
