Opal

-Opal is an anxious noodle. Whenever they feel intimidated or scared, (anything strong along the negative emotions spectrum really-) they will lash out with their heavy tail impulsively. It usually results in some broken bones, and death on rare occasion. They have killed 2 Quetzalcoatls in this manner as of now.

-Opal has what I like to call an enlightened form. The enlightened form is a little something that occurs when a Quetzalcoatl has transcended to a different mental perspective, and becomes enlightened with knowledge. When this happens, their plumes usually grow, and massive spines emerge along their back amongst other physical changes.
