Astral Dragon

The Astral Dragon is the legendary creator of the planet Coryphiel, and protector of all life on the planet. It died many thousands of years ago, but is still respected, and even worshipped, in many societies across the planet.
The Astral Dragon is said to have created many of the magical beings of the planet. In particular, the Eternity Constructs are supposedly created from fragments of its own body, and outlived their creator, in order to continue to protect life.
The current Dragonlords are supposedly formed from the remnants of the Astral Dragon's soul, split into many pieces.
