Baliras are enormous creatures that resemble ocean rays. They have translucent, fleshy wings, and live in the ocean. 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 books several times and are both admired for their beauty and song, and are also 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 they have also been taken down by lightning strikes while flying.
