Summary
As usual, Killer was messing with Cross for attention. Unfortunately for them, Nightmare wasn’t in the mood for their theatrics. If they were going to cut into his free time, Nightmare might as well get some enjoyment out of it.

Summary
Truth be told, Nightmare did not come down to the cellar very often. Usually, there was no reason to; despite the fact that it was where their prison cells were, all of them were empty.
Usually, anyway. It was a bit too risky to allow anyone into the AU he considered his home, if only because of his boys and their safety.
But every rule, even an unwritten one, had exceptions. And today's exception was a spy that Nightmare fully intended to milk for the information he'd gathered.

Summary
After a heated workout, Killer puts some juicy and thought provoking ideas in the horny Cross’ head. Right as their mate Nightmare (who has his female Ecto body on display) is working it in the gym.
Needless to say, Cross can't wait until night falls to see if Killer words are true. Because it's his turn to sleep with his king.-

Brothers In Blood (Sanscest Vampire Poly~) [Hiatus] by orphan_account

Summary
Nightmare and Dream used to live in a quaint little village. The two of them weren't exactly well off, though they made ends meet. One day, however, Dream's entire world was flipped upside down after his brother went missing in the woods near the village hunting grounds. Presumed dead, Dream gradually came to accept that his brother was gone, mourning his loss like one would mourn their late brother.
Except, Nightmare wasn't dead.
Though the truth of what happened to him may very well be worse in the eyes of many.
(This fic is focused on Dreammare, but will contain virtually every ship along the way before the two eventually get together. This is essentially self indulgent Porn with plot, enjoy)

Summary
Written in hidden books in the library of the tree of feelings.
Bonded and claimed since birth.
Nightmare was always meant to be Dreams Omega. Passive and patient to care for negative feelings while his brother cared for positive ones.
But Nightmare didn't want that. And dream was a fucking idiot.
Nightmare thought when he became curroupted his body would be too broken to be Dreams. But the bond stopped him from fully transforming.
And the only way to cut the claim is too find a better Alpha. But Nightmare won't stand around and be a breeding bitch for any Alpha.

Summary
(Title is most certainly a pun and may be changed.)
When you (unwillingly) work for the Church, your view on the world becomes very jaded. It was no different for Error. He hated people, absolutely loathed demons, and wanted nothing more than to die peacefully. Unfortunately, that's wasn't a choice for him, so he soldiered on.
His latest mission - to find and kill the demons at Spiral City with his usual partner, Cross - takes an odd turn, and suddenly, Error's view on the world is changed forever. But does that even matter if he wont get the chance to live with his newfound joy?

Summary
This wasn't how it was suppose to go. Dream felt that he has done everything to get through to Nightmare, but to no avail. But to resort to this? He didn't think things could have gone so south so fast. He just wanted his precious brother back. Was that too much to ask for?
It was an accident.
Now he hurt his brother and he was not sure what to do.
His brother sneered at him. On the other side of the room, another Nightmare glared at him.
There were two Nightmares now.
What has he done?
In which Nightmare does not know what to do with himself and finds a new path.
