Rich, owner of Arminho Ranch and a hotel chain, born from Gregório’s first marriage. His baptism name is Mossoró. He became paraplegic after falling off a horse when he was twelve years old.
His father, Gregório, grew apart from him. His mother, Clarice, got divorced and took the boy to Curacao. Upon realizing he is not Gregório’s biological son, he changes his name to Artur and plans to take revenge using the incest taboo to make Gregório suffer, since Gregório doesn’t know that Artur/Mossoró is not his biological son.
Artur seduces Diana. But he didn’t expect to actually fall in love with her. To continue his vengeance, Artur can’t reveal that they are not siblings, since this would end Gregório’s suffering.
Artur will have to make a choice: either reveal the truth that he is not Gregório’s son and that there was no incest, set hate and vengeance aside, or tell the truth and live his love for Diana.
