Fauna, Companions & Familiars

The floating islands of Caelum host a distinctive aerial fauna shaped by millennia of adaptation to high-altitude conditions. The most culturally significant of Caelum's native creatures is the Stormhawk, a large raptor with hollow metallic-sheen feathers that resonate audibly in strong wind currents. Stormhawks are not domesticated in the conventional sense but have cohabited with Aeriels for as long as any record survives, nesting on the underside ledges of inhabited islands and tolerating — even appearing to seek — Aeriel proximity. They are regarded as sacred by many Aeriels, associated with the Shattered Skies in oral tradition as creatures who survived the catastrophe by flying ahead of it.

Wind-Whales are vast, semi-translucent creatures that drift through the upper sky-layers above even Caelum's highest islands, filter-feeding on the aetheric particles that flow in the high jet currents. They are rarely observed at close range and never interfered with. Among Aeriels they carry a quality of profound reverence — seeing a Wind-Whale at close range is considered a significant omen. Aether-Moths are small, nocturnal insects whose wings carry a bioluminescent charge drawn from ambient magical energy; they swarm in visible clouds around the Skyanchor Pylons at night, drawn to the aeromantic field generated by the enchantments.

Aerial Serpents — long, ribbon-like creatures without wings, sustained aloft by continuous aeromantic body-fields of their own generation — inhabit the cloud-banks around Caelum's outer islands. They are dangerous to approach and capable of disrupting aeromantic enchantments at close range, which makes them a genuine hazard to the Skyanchor Pylon maintenance teams. The Skyguard trains a specialist unit for managing Aerial Serpent incursions. Luminance Finches are small, brilliantly coloured birds that nest in the window-ledges of the Celestial Academy; many scholars keep them as companions, their natural Luminesce-like colour shifts — actually a bioluminescent response to ambient magic — making them useful informal indicators of local magical field strength.
