The Iron-Gilded Mire Cache

While navigating the rust-colored waters of the Järnskogen periphery, you discover a half-sunken wooden crate entangled in the roots of a blackened willow tree. The silt around the crate glows with a faint, oily shimmer, a remnant of the ancient energies that still bleed from the forest floor into the bog iron deposits. It appears to be a discarded haul from a local harvester who fled in a hurry when the wild magics of the woods began to stir.
