Anaon

is a wild creature similar to an undead. One of such is contained within a Goddess Amber used by the Druids of Istar for their training.

Appearance
Anaon looks like a skeleton wrapped in bandages.

Defensive Battle for Liones arc
An Anaon was one of the creatures that Griamore and Slader found in the Cave of Training and ends up turning Griamore into a child, because his greatest fear is to lose all the strength and muscle mass he had acquired in his training and return to be that helpless child. The spell is removed after Veronica kisses him.

Abilities/Equipment
Anaon's main ability is to reach into the psyche of an individual and transform them into whatever creature they fear or detest the most. A kiss from the person the victim loves is all it takes to dispel the magic.

Trivia

 * Anaon is a breton word to refer to the souls of the deceased and the place where they are found.
