The lupin is a variant of the werewolf found in certain regions of France, especially the southern ones. They are said to gather on full-moon nights before the crumbling walls of cemeteries and, standing on their hind legs, speak in an indescribable language.
Another French version of this fantastical being is the Loup-garou, an individual who, in lupine form, goes out to wander during full-moon nights.
