Kudzu is an Emerald Weaver, a dragon that specializes in the creation, alteration, and inspection of dreams.
His eyes must remain closed due to their ability to remain linked to the dream realm, thus letting magic escape as long as his eyes are open. When in the dream world, he may keep them open and see as usual, otherwise he relies on other senses to judge his surroundings.
Kudzu also has a feral form, that of a rather eastern looking dragon (ref to come later).
