Forgotten Worlds
From Spyropedia
The Forgotten Worlds is a kingdom that serves as the setting for Spyro: Year of the Dragon. Originally inhabited by Dragons, when they left, their magical powers left with them. Many of the portals shut down, and the Sorceress emerged as ruler. Spyro defeated the Sorceress, liberated the people, and reactivated many of the broken portals.
A few realms are also present in Spyro: Shadow Legacy.
