Backflow Inducer

The device is a complex assembly of metallic components and glowing conduits, its core pulsing with trapped energy as parts are hastily screwed together. A lattice of copper wiring snakes around its central chamber, connecting to a series of interlocking brass rings that form the inducer's central mechanism. When activated, its purpose becomes clear—it channels and reverses energy back toward its source, a desperate gambit to lure the Keeper into containment before Melkur's corruption completes its takeover.
