Velroc Familiar
 

Velroc is listed in here as a selectable familiar. Is there any official rule that they can be familiars? I am curious if this is official, homebrew, or possibly a mistake when it was added.

The Velroc comes from Dragon Magic. Without a copy of the book I can't check properly whether its meant to be available as a familiar. The book does add a feat called "Drakken Familiar". I suspect whoever coded the user file ticked the Familiar button (and the Paladin Mount button too oddly enough) by mistake.
