Rustshade Lurker

Field account

The rust streak on the tank had shoulders. Once I saw them, the rest of the Lurker unfolded: a narrow head, long hands, and torn afterimages the color of old blood on iron. It waited until Sela leaned against the rail, then came through the corrosion beneath her palm. The metal failed at the same instant. She fell; the ghost followed, using the broken rail as a spray of orange cover. A Rustshade does not pass through sound iron. It inhabits neglect—the wet seam under a bolt, the hollow beneath a painted plate, the stain everyone has stopped inspecting. We drove ours into a polished wrench head by scraping every other rust patch with wire brushes. Trapped in that small surface, it could not stretch its arms. The safest rail in its territory is the one you have personally cleaned.

Observed behavior

The Lurker chooses a corroded support already likely to be trusted, waits for weight, then emerges with a sudden rear strike as the metal fails. It retreats into another rust patch rather than holding a solid body. Fresh abrasion drives it along the connected structure, allowing hunters to herd it by cleaning from several directions. Water spreads its possible refuge; oil denies it. The ghost avoids open stone and clean timber. When cornered in a small rusted object, it becomes dense enough to seize or destroy.
