Vidorian of Thistledown was one of the only two monarchs to complete The Gauntlet and earn the title of "Dark Master" and a Shadow Stone - a unique upgrade stone for Atlan Weapons. As a Dark Master, she was later called on to help Bael'Zharon's generals destroy the last of the Soul Crystals, the Shard of the Herald, which she eventually destroyed using her Peerless Shadow Atlan Dagger.
