Summary
He didn't manage to even get four hours of shut eye before waking up from his nightmares. So he was pretty out of it. He even had to slide down on his bottom on the second half of stairs just to not risk falling down them.
He made it to the kitchen with, of course, difficulty. Falling over one of the bored games, he and his best bruh played a few nights before. He mentally noted to fix the mess he made once he finally got what he was aiming for....Wait, what was he even looking for again?— Right! His life-saving substance! Coffee!
He checked the fridge for one of his outerbucks, letting out a quiet, desperate whine once he saw there wasn't any. Extra work. Great.

The Multiverse is vast and nigh infinite, possibilities, concepts, the very function of a world's reality only limited by sheer creativity.

The tragedy of it's Story forced to continue beyond it's Endings, for it forced the concept of Balance into the Multiverse's rules. Now open-ended, the only two Characters wanders throughout the Multiverse as one of it's Outcodes.
Dream broke out of stone to one colorful and curious Inkblot, so much to comprehend for someone so small. But alive nonetheless.
Nightmare woke up freshly dead.

Summary
On the ice, Cross knows exactly who he is.
Hockey is noise and impact and certainty—early mornings, aching muscles, and the comfort of rules that never change. The rink has always made sense to him. Until one quiet practice, when his focus drifts to the far end of the ice… and to Dream.
Dream skates like the world is holding its breath for him. Alone, graceful, and seemingly untouched by the chaos around him, he moves with a softness Cross has never learned how to name. They share the same rink, the same cold air, but live in completely different worlds—one built on force, the other on trust.
As practices overlap and glances linger, Cross begins to notice the spaces between collisions, the silence beneath the noise. And Dream, used to skating alone, starts to wonder what it would feel like to be seen.
Set beneath bright rink lights and winter mornings, this is a story about two boys moving in opposite directions, until the ice pulls them closer. About finding connection in quiet moments. About learning that sometimes, the most powerful thing isn’t how hard you hit the ice… but how gently you glide across it.

Summary
“Hey, uh, hey, boss. What’s up?”
Killer stood, alone, in the empty hall that made up Nightmare’s throne room. Horror and Dust, as useful as they’d always been to him, he hadn’t summoned. Nightmare would need to, sometime, but this… he had reasoned to himself that this, perhaps, was something done better with just the two of them, face to face. More personal. So Killer stood in the grand hall, hands shoved into the pockets of his jacket, his near-perpetual smile unfailing.
And completely, entirely, utterly at Nightmare’s mercy.
Nightmare reflects. Then he does something about it; something he once never would have.
He lets them go.
