[Each chapter of this book describes the cultural origins of a different mythological beast.]
Chapter 5
Very little is known about this particular cryptid, though stories say they tend to choose well-muscled human males as their steeds when they deign to visit this plane. According to legends, this creature retains a wellspring of indescribable power known only to itself, though it provides its steed with perhaps mystical, perhaps mundane courage. Unsubstantiated rumours claim the creature has a taste for human eyes.
