The Lantern Keeper’s Bargain

The first time I saw the lantern, I thought it was a trick of the light—a firefly caught in the mist that rolled off the marsh. But fireflies don’t hover at eye level, and they don’t pulse with a sickly green glow. I was fourteen, visiting my aunt’s farm in the backwoods of Maine, and the path from the main road to her house was a winding dirt track bordered by gnarled willows and the skeletal remains of a tannery that had burned down decades ago. Everyone in the county knew the story: the tannery’s owner, a miser named Ephraim Cole, had vanished the night of the fire, leaving behind only a charred lantern found hanging from a rusted hook by the gate. They said he’d made a deal with something in the swamp to keep his business alive, and when the deal came due, so did he.

I never believed it. Not until that first night.

My aunt had sent me to fetch water from the well at the edge of the property, and as I walked back with the bucket, I saw it—a ghostly flame bobbing along the treeline, moving in a deliberate, patient rhythm. Not like a will-o’-the-wisp, which dance and dart. This was a steady pulse, as if carried by someone walking. I stood frozen, and it stopped too, as if it knew I was watching. The air grew cold, and the smell of smoke and rot filled my nostrils. I ran back to the house, slammed the door, and told my aunt. She went pale, but said nothing. Just told me to stay inside after dark.

But curiosity gnawed at me. The next day, I went exploring. The tannery ruins were still there—blackened beams, a broken chimney, and a rusted iron door leading to a basement that yawned like a hungry mouth. Inside, I found a workbench covered in old tools and a journal. The pages were brittle, but the ink was still legible, written in a cramped, sloping hand. It was Ephraim’s diary. He’d written about the things he’d seen in the swamp—”the eyes that watch from the cattails”—and about the bargain he’d struck with something that called itself the Keeper. The Keeper would give him success, but in return, it would take his first-born child. But Ephraim had no children, and he thought himself clever. He forgot that the bargain could be transferred, that anyone who printed the Keeper’s lantern would be bound instead.

I should have burned the journal. But instead, I pocketed it, and that night, I saw the lantern again, closer this time, right at the edge of the front porch. It hovered there, and I swear I heard a voice—a sibilant whisper that came from the flame itself—saying, ‘Take the lantern, and you’ll never want for anything. Just light it when I call.’ I was young and foolish. I reached out and touched the glass.

The moment my fingers made contact, the flame turned a deep red, and the world tilted. I saw the swamp through the lantern’s glow, and I saw things moving in it—shapes that were half-human, half-beast, their eyes gleaming like the starless sky. And I understood: by touching it, I had accepted the bargain. The Keeper had its new servant. The diary had warned that the only way to break the bond was to pass it on, to find another fool to touch the lantern before the next full moon.

I spent the next days in a panic, trying to find a way out. I couldn’t tell my aunt; she was a devout woman who would have said it was a test from the Lord. So I stayed awake at night, watching the lantern pulse outside my window, growing brighter each evening. I tried to destroy it, but it was always just out of reach, and when I got close, the air would thicken, and the voice would hiss, ‘Not yet.’ I tried to dig a hole and bury it, but every time I uncovered a fresh patch of earth, the lantern was there, waiting, its glow like a patient predator.

The full moon arrived on a sultry night. The marsh was alive with the sounds of frogs and insects, but I heard nothing but the drumming of my own heart. I knew I had to act. I remembered the old stories my grandmother used to tell—about how to break a bargain you had to give the Keeper something it wanted more. But what could a swamp spirit want that I could offer? Then I thought of the diary. There had been a second part, written in the margins, in a different hand—perhaps the hand of someone who had been in my position before. It said: ‘The Keeper prizes names. Give it a name that hasn’t been spoken in a century, and it will release you.’

I searched the family records. There was a grave behind the old church, from the 1800s, of a woman named Hester Vane. No one had spoken her name in ages. That night, under the full moon, I stood at the marsh’s edge, the lantern in my hand. I shouted, ‘Hester Vane! I give you her name!’ The lantern flared, and the swamp erupted. The creatures rose from the black water, and the Keeper itself manifested—a towering figure of twisted roots and glowing embers. It reached out with a clawed hand, and I thought it would take my soul. But then it paused. It turned its head, as if listening, and then with a terrible growl, it vanished. The lantern’s flame flickered and died.

I dropped it, and it turned to ash. I thought I was free. But as I turned to leave, I heard a voice behind me, soft and mocking. ‘Clever child. But names can be reused. And you’ve given me a name that still has a living bearer.’ I spun around, and there, standing in the reeds, was a girl my age, with skin that glowed faintly green. She smiled, and her eyes were pits of black. ‘You’ve bound me to you, little lamb. I will follow you until I take my due.’

I never saw the lantern again, but I’ve never been alone. Sometimes, when I glance into a puddle or a mirror, I see her reflection just over my shoulder. And at night, I hear her humming an old hymn, the one they sang at Ephraim’s funeral. She’s patient. She knows I’ll trip up eventually. She knows that the only way to rid myself of her is to find another soul to take my place. I’ve grown older, but she hasn’t changed. And I’ve started to wonder—if I can’t find a victim, could I become the Keeper myself? Maybe then, I’d be the one to call the shots. But that might be just what she wants. She’s been waiting for a successor all along.

The last time I saw her, she was standing at my gate, holding a lantern. Its flame was a sickly green. She winked, and mouthed, ‘Soon.’ I haven’t slept since. I’m writing this to warn you—if you ever see a lonely light in the mist, don’t approach it. Don’t touch it. And whatever you do, never give it your name.
