Thomasin, also known as The Lady, is a dragon of unsure origin. Believed by many to be a spirit, she is responsible for the behind-the-scenes formation of the Coven. She is a guiding voice to all of the members, luring in outsiders to join. She is soft-spoken and often whispers, her kind nature persuading many to follow her deep into Dragonhome.

Thomasin has the ability to bestow mystic gifts upon members of the Coven. Rituals allow her followers to go beyond their own elemental abilities, tapping into other elements as well as ancient powers. Suddenly, wind dragons could manipulate stone, and nature dragons could contaminate the plants that they care so deeply for. These powers are very slight, and only work when a member of the Coven is near the others.

It is believed that the reason Thomasin chose Dragonhome as the Coven's base is because of the World Pillar, and Dragonhome's connections to the other flights. The manipulation of elements outside of one's birthright is not possible outside of Dragonhome, and not possible without the other members of the Coven being near. How The Lady came across this find is unknown.

The Coven doesn't know of The Lady's intentions for them, if there is any intention at all.
