Baliras are enormous creatures that resemble ocean rays. They have translucent, fleshy wings and live in the ocean, where they migrate to Estenzia to give birth in the shallow warm waters. Baliras have the capability to swim in water as well as fly in the air. They are featured in the book several times and are used as a means of transportation. Despite their strength, many of the baliras are found dead on the beach after being affected by supernatural powers in the water, and have been taken down by lightning strikes while flying.
