The Backpack Mimic, the Dead Man’s Kit
“A company rule, as old as the roads: whoever picks it up carries it.”The mimic is a demon that takes residence in an object and assumes its substance, its grain, its smell, down to the stitching. This one inhabits a backpack, because an abandoned pack nearly always gets searched. The pack existed before the demon did, and so did everything hanging from its straps: the tin cup, the flask, the rolled blanket all belonged to someone.
Appearance
You spot it. A pack sits against the wall, as if dropped by someone who meant to come back. It is placed too well, right in the middle of the passage, and a clear puddle spreads slowly beneath the leather. When you stop, the cup knocks against the flask, though the air is perfectly still.
The ambush. The pack is heavy, and something inside clinks like a well-filled purse. You lean down to undo the strap that holds the flap shut. It resists under your fingers, taut and warm as a muscle. Then the flap lifts on its own, and a wet tongue seizes your wrist.Combat
How it fights. It smothers its own magic as thoroughly as its shape, and nothing gives it away at first glance. Its prehensile tongue grips a wrist or an ankle and hauls the prey toward the maw. Its saliva keeps blood from clotting: an ordinary bite keeps bleeding long after the fight is over.
How to fight it. It hides its demonic nature, but not the life it breathes into the leather to move it. A skilled mage searching for magic will find residual traces of life magic on the pack, where no leather should carry any. An incarnate demon can be banished: the pack then falls still, exactly as it was before, with everything it held.A Backpack Mimic token depicting a worn leather traveler's pack equipped with a bedroll, tin cup, and flask, concealing a large fanged maw with a prehensile tongue and dripping saliva.
