Sun leans back into the couch, his rays drooping with a quiet exhaustion. Moon moves softly between the children in the Daycare, his voice a low murmur. Lunar’s laughter echoes from inside the play structure where he leads a game. Outside, in the damp alley, Bloodmoon crouches over his grim meal. Behind a sealed door, Eclipse solders wires to a pulsing core. Solar sighs, running a diagnostic on the flickering terminal. In a corner, Jack and Dazzle build a fortress of plush toys, their whispers weaving a shared world.
