Summary
In the year 40XX humans and monsters have successfully established colonies in planets far away from our own, in other galaxies. Polaris VI is one of the many missions to deliver supplies to a space station overseeing one such colony. With Cross as the commander, Killer as the pilot, Dust as the medical staff onboard, and Horror as the engineer, this mission should be successful and be back on earth ten years after departure, as scheduled… little do they know this mission will change their lives forever.
Updates every monday!

Summary
"I'm sorry to hold you hostage," Sol said, hands lifted in mock contrition. His smile was all teeth, bright and blasphemous. "I just couldn’t help myself."
Nightmare stared him down, unamused. His voice was cool, but laced with simmering disgust. "You’re not sorry."

Summary
He can’t look away.
Cross, kneeling before him, head bowed like penance, like prayer. Like a soldier returning not from victory, but from surrender.
Shattered is... fascinated. Amused. Disbelieving. The X-Event, brought low. Offering himself like tribute.

Summary
NIGHTMARE has everything he could ever want- power, godhood, a bloodline, total control, and a partner who worships his every step. He had a few inconveniences along the way, but he could handle them with ease. His focus is now on raising his daughter and taking care of his wife and team. Despite being much more relaxed, he's still a deadly threat.
CORE FRISK is the only surviving hero. The Star Sanses and even Error are either dead, infected, or brainwashed. They're running the DRA, the Doodlesphere Rescue Alliance, and have three current goals. One, find a cure to the parasite running rampant through the multiverse. Two, find a way to save their friends from Nightmare's mind control. Three, kill the king himself and restore peace to everyone. But that . . . is much more difficult than they can manage.
DREAM is the heartless ruler of the Omega Timeline. Trapped under Nightmare's spell, he has no empathy for anyone. He hasn't had any for the past 7 years. Yet something still haunts him. The cursed gold heart locket he always wore, that he hated, yet couldn't find the heart to get rid of. It gave him the motivation to fight back, so did the corruption in his soul and his smoking addiction slowly killing him.

Summary
Falling.
You were falling.
…Or were you?
You were weightless; both falling and floating; suspended in midair, nothing below your feet, but also no air flying past your face or whipping your hair around to tell of gravity’s play of hand.
And it was dark.
Suddenly, in the middle of the far distance, a white light appeared. With each passing second, it was growing bigger, bigger, and bigger still.
You realized, belatedly, that the light was drawing you in, tugging at your very being, and something about it was… awakening something within you.
The light grew closer, and your hope stirred.
You hadn’t wanted to die. You didn’t want to die.
You looked up into the light, and you reached out with everything you had.
With one final tug, the light pulled you into its embrace.
And just as tightly, you held on.

Summary
Шла, шла и умерла. Мало того, что умерла как лох, так ещё и после смерти покоя нет. Без моего согласия запихнули в глючную задницу всего мультиверса! Мою любимую Ошибку, конечно, но всё же! Не хочу быть разрушителем вселенных. Работа эта неблагодарная, опасная. Так ещё и без зарплаты и отпуска. Идите все нафиг, я сбегаю. Пусть в этой мультивселенной хоть коллапс произойдёт от переизбытка мусорных вселенных! Мне плевать!

Summary
“You’re trembling,” Sol murmured, delighted. His voice was syrupy, cloying, a honeyed lullaby laced with thorns. “Worked up already, baby?”
Nightmare convulsed beneath him—struggling, snarling, humiliated. He twitched, spasmed against the chains. His limbs jerked without rhythm. He didn’t have control anymore, not really.
And Sol knew it.
