Summary
In a cold, sterile facility designed for containing the extraordinary and the dangerous, selected individuals with unique abilities—or curses—are kept under constant observation. One of them is Fyodor, who has the ability to infect people's minds with parasites. In ways they cannot fully comprehend, scientists like Nikolai, a man on the verge of losing control, and Sigma, a determined but unraveling person, are drawn into his presence. (A recycle of my SCP AU for OCs lol)

Summary
As a tactical technology company, the DOA Corp is quite possibly one of the most successful businesses in the country. Only the top people in their fields can even dream of walking into its headquarters. The firm was only founded a mere decade and a half ago, though it's very well known in the world of business.
About a week ago, the DOA Corp found themselves a brand new intern. Sigma, a bright young man with excellent memory skills, managed to acquire an internship on one of the upper levels of the building. He would be doing tasks for people that are a few layers beneath the CEO himself.
or, a DOA Business AU for an excuse to write office smut ;p

Summary
“I wouldn’t trash talk you behind your back, that I can tell you.” Sigma managed to say, not faltering despite having Nikolai’s full attention on him by virtue of a miracle, probably.
“No?” His innocent look only increased. Damn, he was good. “Not even on my first day here, where I gave you that super-duper complicated order?”
There, they couldn’t help but burst into laughter.
siglai au where sigma's a barista, nikolai's a magician at a nearby theather, and they quickly pique each other's interest.

Summary
“Ah, don’t worry! One of your friends tried to bite me and partly succeeded, that’s all.” That made them laugh a little; it wasn’t uncommon for fighting, given how most preferred their own sharp teeth over any weapon. “What? You might have too?”
“Maybe.” They simply replied, and the word sounded more amused than menacing, something Sigma couldn’t say had been accidental.

mermaid/pirate siglai au, and their first meeting.

"Movie night in my house," Dazai said.
"Just between friends,"

Summary
Sigma said, “That’s the worst sentence you’ve ever spoken to me. A new record. A truly astounding accomplishment after— what, no, I absolutely do not need to be teleported right now, this is the absolute worst time for me to—”
“Disappear!” he cackled, diving across the table.
It was a beautiful day in Sigma’s favorite office, and Gogol was a horrible nuisance.
Or: Gogol takes Sigma on a tour of his Overcoat pocket. Antics ensue.

Summary
Sigma kept holding their breath, a few moments had now passed...how strange. Shouldn't they...took a deep breath. They had shocked look on their face. Able to breathe under water... did they die from the fall and now were they in the afterlife, how strange. It was quite calm and felt peaceful... Was this it though, falling endless done this body of water... it's been so long, well at least that's what sigma thought, it felt like hours or was it minutes, it was confusing.
