Aether Wasps

Aether Wasps
Aether Wasps are iridescent, crystalline insects that thrive in high-density Aether fields. Unlike common wasps, they do not feed on nectar, but on raw magical energy. They are most commonly found swarming around "bleeding" Aether-pipelines in Steamfort or nesting in the mana-sumps of Kigum. Individually, an Aether Wasp is a mere nuisance, but in a swarm, they can drain a seasoned mage of their power in seconds.
Their wings emit a high-pitched, melodic hum that can harmonize with active spells, often causing them to "flicker" or fail entirely.
Secret Motivation: The wasps are actually a biological mechanism developed by the Ancient Aether-Spirits to regulate mana-leakage. They are attracted to unstable magic and seek to "seal" it by consuming the excess energy.
Adventure Hook: A major Aether-node in the Kigum Spire has been infested by a massive swarm of Aether Wasps. The city's lighting is failing, and the floating sectors are beginning to drift. The party is hired to "clear the nest" without damaging the delicate node.
