A kingdom ruled by Queen Angella, mother of Princess Glimmer. Angella possesses extremely powerful magic, whose potency is more than sufficient to prevent the Horde from attacking her kingdom. Her magic is however tied to the powers of Castle Brightmoon and its Moonstone gem, which themselves are derived from the light of Etheria's triple moons. When the moons are darkened during lunar eclipses, her magic fades to almost nothing, leaving her kingdom vulnerable to attack.

Brightmoon was the last Etherian kingdom to fall to the Horde's initial invasion, and the first (and only verified) one to regain its freedom. It is often utilized as a staging base for rebel activities.
