Peryton

A type of wyvern. There are no records of these wyverns ever attacking humans, and were known as being harmless and non-territorial, but in recent years the perytons have become aggressive, and are now randomly attacking any human it encounters. Some researchers have pointed out that this change came from the over excavation of crystals conducted by the Aldore Empire, but with the mysterious deaths of these same researchers, many soon turned a blind eye to this subject.
