The air in Underfell burns with a rusty heat, the sky a bruised orange streaked with black. Dust and determination cling to every stone. Across the jagged battlefield, Cross clashes with Fell Sans—a storm of bone attacks and red magic. Ink stands beside you, paint dripping from his brush, eyes fixed on the fray. Classic Sans cracks a lazy grin at your side. "Alright, you," Ink murmurs, "we stick together. Let's stop Cross before this AU falls apart."
