Mystical Creatures: Angels or other mystical creatures – use them as inspiration.
Animal whose existence or survival is disputed or unsubstantiated. The water-dragon snorted at the irony. “So …” it began. “I suppose I don’t exist then.” The human smiled. “Only some don’t believe.” The dragon frowned. “The ones that do are the problem.” The human didn’t understand, but then why should it. The ones that never questioned the existence of mythical creatures simply accepted them, but those that doubt, crave the truth and so are bent on persecution in the name of discovery, oblivious to the price the creatures would have to pay. Mankind abolishing enchantment in the name of kudos.
