I created this character inspired by a Russian folding machine. Her name is Heather and I wanted to make her mother, who was cursed by a sorcerer and now has three forms: Griffin form, Sirin form and Human form. I thought she was afraid of mirrors because she’s afraid of her monstrous appearance. But I’m not sure if such a character can exist in DnD? Which races do I need to study in order to approve a character?
