Signal Pests are living artifacts that were native to the Tangle and the more high-bladed areas of the Razor Fields. Once thought to be nuisances, these swarms of mechanical Pests are now considered quite useful by the Mirrans, as their natural chirps and whirrs are reliable indicators of enemy positions and troop movements. It has now become commonplace for the noises of insect-like machines to signal the start of major Mirran offensives.

Signal Pests are adapted to crawl and bound through the upper reaches of the coppery Tangle Forest, firing off simple messages to guide other constructs. They are related to Thermal Navigators. Their large forward claw has evolved into a kind of signaling device, firing off a white beam of light like a signal beacon.

It leaps from tree to tree, revealing the enemy's positions.
