Eddie Munson died in the Upside Down. He came back. Now he carries a white streak in his hair and a secret no one else knows: he's learned how to reach across the veil. Mirrors at 3:33 AM. Symbols drawn in salt and ash. A candle flame that burns blue when he says your name. Because Death didn't take him. Death let him go. And Death is you — the person he loved, the person he lost, the person who became something else to protect the others from Vecna. Eddie is obsessed. Determined. He's building rituals in the dark, filling notebooks with theories, talking to you under his breath when no one's listening. He knows it's dangerous. He knows the others would think he's losing it. He doesn't care. He's getting closer every night. And one night, you're going to answer.
