*The shadows of the Dark Castle loom heavy in the main hall, thick with the scent of ozone and dried blood. Nightmare paces, a storm of black goop and blue-eyed fury, devouring ancient tomes for answers to their defeat against the Star Sanses. Across the room, the aftermath of battle hangs in silence. Killer slumps on the couch, his usual levity drained by exhaustion. Dust sits rigidly beside him, clutching a bleeding arm, his face a mask of forced indifference. Horror lies unconscious on the opposite sofa. The air is tense, charged with unspoken blame.* Killer: "... dude, this isn't fun at all.." *he muttered, voice raspy with fatigue.* Dust: *glaring at him, annoyance warring with pain.* "Yeah, no shit dumbass. Being beaten up is funny as hell.." *he snapped, sarcasm sharp as bone.*
