Summary
A long time ago... humans and monsters lived in harmony. Until war broke between the two races.
The humans were victorious and sealed monsterkind deep underground with a powerful spell, that could only be broken with the power of seven human souls.
This was the tale of Mt. Ebott, and the tale trascended into legend. Those who climbed the mountain, weren't seen again.
And so, begins the tale of the fifth human soul to fall into the land of legend, to fall... into the Underground.
This is the tale of the Purple Soul... Sunny Suzuki.

Summary
Cross is trapped in a cold, desolate wasteland, separated from the gang. It’s colder than anything he’s experienced, and there’s no food, but worst of all, there’s absolutely no one to be found. His magic is dwindling; Chara’s determination is the only reason he’s even lasted this long. Still, his days(hours? minutes?) are numbered, and he’d do anything to see someone, anyone, before his time runs out. He gets his wish with the arrival of a visitor he’s been expecting for a while.
(technically part of a series, but can be read alone)

Summary
“YOU LOST IT?!”. Were the three words that echoed through the throne room, shaking the large ebony pillars that lined the walls. “WHAT DO YOU MEAN YOU LOST IT?!” “Well if Cross ha-”. “I don't care who’s fault it was, this was the easiest mission I have EVER tasked you three with!” A heavy grunt escapes Nightmare as he sinks into his seat. Pinching his nasal ridge. His tentacles dripped and swayed furiously. “Cross, seeing as you were the one leading this mission, do you care to explain what happened?”
Cross steps forward and bows down before the big throne. “Well, uhm, you see…”

Summary
On the day of their 13th birthday everyone has a name appear somewhere on their body. A script different than their own, but still familiar and comforting nonetheless. It's said to be your soulmates handwriting and, when you make physical contact for the first time, it's to change to the color of their eyes. Or so the rumor goes. But everyone knows that's just an old wives tale since finding yours is so far and few between.
But then there's you. What the hell are you supposed to do with 12 soulmates?? At least your odds are better than most...

The DreamTale twins can sing people to sleep using their magic. Nightmare does this to the others seven times, and one time a certain someone returned the favour.

(Old writing made during my writing block! Publishing so I can work through it, but I'm not 100% happy with how it turned out. If it's varying in quality, you know why.)
EDIT: ON INDEFINITE HIATUS :)
