Been re-watching W.I.T.C.H. and drew up some Phobos x Cedric from a personal, post-Season 2 AU.

Cedric is in a botched (he's smaller and the hind legs are a bit too short), half-transformed state and can no longer shapeshift. Phobos is also powerless and is reduced to an impertinent chew toy.

With Elyon's extremely tentative permission and constant surveillance, Cedric is left as a book/records keeper/restorer at the castle while Phobos is a passive nuisance.
