Castell

Castell, portrayed by Benedict Campbell, is an elderly magic friend who is the teacher at The School in the Sky where young magic friends attend. He has an identical twin brother named Antonio who works in his garden. Castell typically speaks with a Mexican accent and is likely named for the Aztec deity Castellcoatl. He tries to encourage his young charges to find solutions to their problems on their own, but is a sounding board who offers stability and comfort, as well as sound advice. In the episode 'Snow Magic Friends,' Castell mentions it has been hundreds of years since he visited the magic snow sculpture as a child, implying he is centuries old.
