WHAT IS THE ORIGIN OF STYGIAN?
Stygian originally referred to Styx, one of the mythological rivers of the underworld. Ancient Greek Stýx likely shares an origin with several words relating to hatred, and the Greeks once believed that swearing on the river’s name created an unbreakable vow. Stygian was first recorded in English in the 1560s.

Stygian Owl (from acbbirds.org):
The Stygian Owl is one of the more mysterious members of an already elusive, often misunderstood family of birds. This owl's vivid, orange-yellow eyes glow bright red when illuminated by artificial light, and with some creativity, its long, close-set ear tufts can appear to be horns.
