Also called a "Child of Change," not much is known about the species as a whole, due to there being only one known specimen.
Meinastoirim are small rabbitish creatures with round bodies, stubby legs, and large feathered ears that they use to fly with. Their eyes have a horizontally slitted pupil, making their faces look somewhat toad-like. Assuming Meinya is not an exception, they are friendly, vocal animals, and can form strong bonds with humans.
Meinastoirim have pliant, flexible bones that can undergo a lot of stress. When Meinya was injured, rather than being crushed, her eyes were pushed out of their sockets, and her intestines out of her anus, before being popped back in with relative ease.
