The penultimate journey

A weird creature takes up residence in a villa owned by an aristocratic family whose members reluctantly accept his uninvited presence. Their coexistence goes on for years and the weird creature is at first the object of the family's curiosity and subsequent tolerance whereas itself is indifferent and aloof. They are ultimately two worlds apart and never really meet. Time passes slowly, family life drags on, caged by the rigid rules of the civilized world while the strange guest has an energy within it that suddenly goads it to leave the house after 15 years lest it fall into a depression. One year on, following the disappearance of the weird creature and the subsequent demise of the Marquis's wife, the family members experience a kind of rebirth. The disappearance of their strange guest and the death in the family induce a sort of curiosity and desire to go on a perilous quest for their old sometimes missed guest/friend through distant and exotic places. At the end of their trek they will reunite with their old visitor and discover their inner selves possibly finding the true meaning of their existence.
