Celestial Heirloom

The Celestial Heirloom, sometimes referred to as just the Heirloom, and prior to the fall of House Pure it was known as the Arcane Charm.
The Celestial Heirloom is a dense concentration of arcane magic, taking on the form of a large golden jewel. It is the earliest known Celestial artifact, and it was created by Lium, Iris, and Lale so that Celestial magic may be passed down from generation to generation.
