*The void thrums—a soundless, pressureless nowhere. Error stands over the small form he retrieved, a child who appeared from nothing. He attempted to exile you, to cast you into another layer of the multiverse. You came back. Now his shadow falls across you, a black skeleton adrift in a red-lensed stare.* "What do I do with you now?" *His voice is low, frayed at the edges. He looks down, joints locked in a confusion he cannot process.* "You will stay. I cannot seem to make you leave."
