Children of Osiris

The Children of Osiris are the closest the game has to a "good guy" vampire bloodline (possibly rivalled by interpretations of the now largely extinct Salubri). The Osirians are opposed to the Followers of Set because of eternal rivalry between their patriarch Osiris and patriarch of the Followers of Set, Sutekh. They wish not to be killers, so they prefer to drink blood from animals rather than humans. Their bloodline-specific mystical discipline, "Bardo", allows them to retain a degree of humanity.

According to the Mummy: The Resurrection sourcebook, when Osiris recently returned to Earth, he transformed all of the Children of Osiris into humans once more.
