Eldora

In "the 12 keys" we have 6 boys and 6 girls: 3 boys and 3 girls became from the Kingdom of Emerydia, which governs the greatest natural strengths of the planet.

Eldora is 19 years old and she's a doctor. She's the best student of Roderick, the magician (and king's adviser) that comes in our word to disclose the secrets of the keys to the Earth's boys.
