Yna Yandak would be in my fictional language of the Iknayaru people (which my indigenous human OC Alaya is part of) and it would mean “Fire Spirit” (Maybe in a textbook translation 😆)
They would be the spirits of warriors who won’t rest until they take vengeance on their enemies that slew them in their life. Though sometimes, in some way of a ritual, they could be summoned for another one’s similar bidding.

Done with a few yellow (specially Light and Ivory yellows), bright orange colored pencils and then with a charcoal pencil.
