Believing is just the beginning with Tinker Bell and all her Disney Fairies friends. Pixie Hollow is the secret world where Fairies live and work to create the four seasons to take to the Mainland.
The four areas are called Spring Valley, Summer Glade, Autumn Forest and the Winter Woods. The Pixie Dust Tree is at the heart of Pixie Hollow. It's visible from everywhere and its roots spread across the entirety of Pixie Hollow. Queen Clarion lives in the Pixie Dust Tree, watching over the whole of Pixie Hollow.
