Stygai is said to be a haunted corpse city. Twisted creatures, such as demons and dragons, are said to live in its vicinity, and even shadowbinders fear it. Little is known of Stygai, bar that its byname comes from the fact it only sees the light of the sun for a brief period of time each day, around noon.
Behind the scenes
The name "Stygai" may be a nod to "Stygia" from the story “Shadows in the Moonlight” by Robert E. Howard. In an essay in his Dreamsongs anthology Martin cites reading Howard's story as a formative experience in his (Martin's) development as a reader of fantasy. Martin quotes to a passage referring to Stygia "with its shadow-guarded tombs."
