The Griffin's FeatherThe Griffin's Feather

Ben and his adopted parents are devoting their lives to protecting rare and fabulous creatures (like dragons) and at the moment they are trying to save the last of the winged horses, Pegasus unicus; there are three eggs, but without their mother they will not survive and the only hope is to obtain a Griffin feather--but Griffins are enemies of the dragons, and may not be willing to help.
