Tales of Tolgard
Firestars, also known as the moon dancers, are tiny glowing beings that roam forests and hills, and generally ignore travelers. They appear as silent, floating, fist-sized motes of light, and are frequently will-o’-the-wisps or torches.
These aberrations can consciously control their illumination level, from bright torchlight to total darkness. During a blackout, they are effectively invisible. The light fails completely when the firestar dies.
The firestars’ language consists of intricate patterns of flashing lights, accompanied by fluctuations in their light level. They understand some humanoid gestures, movements, and languages.
