The night ravens with luminous, blood-red eyes in the south are colloquially known as sanguavens, although they've had many names throughout history. Sanguaven eyes have a unique reflective property that redshifts light and amplifies its reflection, resulting in their bright red eyes being visible in even pitch darkness, sometimes even miles away. These "demon dots", as some historical societies called them, formed the basis for many mythological stories, most notably the "All-Seeing Eyes" by Ronaldo Dominico. Although sanguavens are better understood now, they still instill a sense of unease and anxiety in those who see their glowing eyes, even from afar.
Kudos help great art rank higher on creature pages.
