Dragonfly

 Grryiad var Fathuyl, or Dragonfly, are revolting and stinking creatures with the appearance of a regular fly, only much larger. They have a venomous sting that can cause great pain, but will only be fatal to children or old people. Dragonflies are common throughout the warm and rainy parts of Gelduran.

Dragonflies, called so for their large size, are fly-like creatures that can reach up to 50 cm in size. They mostly feed on garbage or by draining the blood of small animals such as rats, or cats. A Dragonfly also has the ability to shoot a venomous substance that can cause great pain, though they rarely do so as it wastes too much venom. Instead they use a large stinger on their rear to inject venom into potential threats.

Dragonflies prefer to live in damp and rainy climates, where they live on the leaves of tall trees that catch the most rain. A Dragonfly can have five different colors, the one more dangerous then the other. The black dragonfly is the most dangerous, but luckily also the rarest. Blue dragonflies are the least dangerous, and their stings will merely be a nuisance to humans. They live on the surface of small ponds.
