Arcane Acre is the school where Sela Mathers, Shang, and Belinda have taught students since about a year after the events from the Realm War were fixed. Students include Sela's daughter, Skye Mathers, the current Mad Hatter of Wonderland, Violet Liddle, a water nymph from Neverland named Hailey, and Wulf and Ali both of Myst.
There is a graveyard near the school that is considered to be the most haunted place on Earth, something that the skeptical students had a hard time believing when Shang told them. Wulf and Violet's desire to prove it wrong almost got all five of them stuck in eternal nightmares.
For Belinda it is a chance to start over once she is taking definite advantage of and enjoying the chance to help people rather than hurt them, but the lack of belief from others still has the power to hurt her.
