Penumbra Island is the home of Anthony and Chesska Solair. It was left to Anthony by an uncle of his. The island is described as cold and damp, which is probably why no one else in the Solair family cared if Anthony took it.
Not much is known about it, aside from how there is a secret tunnel hidden beneath the island as a sub port, riddled with dragon traps Anthony set as a security measure, and the giant space ship that forms the island's foundation.
- A penumbra is defined as the part of a shadow that only partially lets light touch it; a border between light and dark. This is fitting considering how the Great Raven is sealed in the island's heart and bordered on all sides by the forces of good and light.
