“A gaunt, foul-smelling dog-man who haunts the graveyards as the Guaraní lord of death.”
The seventh and last son of Tau and Kerana drew the heaviest share of the curse. Luisón is the Guaraní lord of death: a gaunt thing caught between man and enormous dog, long-haired, horrendous to look at, trailing the stench of rot wherever it goes. It keeps to cemeteries and the night, feeding on the dead, and tradition holds that merely to see it is to be marked — an omen that death has taken notice of you.
No other member of the seven traveled so far. When European settlers carried werewolf belief into the Río de la Plata, it fused with Luisón and with the region's own maned wolf to produce the lobizón — the cursed seventh son of Paraguayan, Argentine, and Uruguayan folklore. The old cemetery god became a transformation curse, and the fear it generated proved real enough that governments eventually got involved.
The Legend
Tau, the spirit of evil, stole Kerana and fathered seven sons upon her, each cursed to monstrosity by the high goddess Arasy. Luisón came last, and the tellings agree he was the most dreadful: a giant dog, extremely ugly, even horrendous, with matted hair and a smell of death and decay that announced him before he could be seen. His dominion was death and everything belonging to it.
He kept to burial grounds and the dark hours, a corpse-eater haunting the resting places of the dead. Where his brothers ruled caves, wetlands, open fields, and forests, Luisón's kingdom was the grave itself. To cross his path at night was understood as a sentence: the sight of the Lord of Death meant that death would shortly return the visit.
The Record
The seven-brothers cycle entered print with Narciso R. Colmán's Ñande Ypy Kuéra (1929), and ethnographers such as León Cadogan documented the persistence of the Guaraní pantheon in rural Paraguay long after lesser gods were forgotten. Luisón is consistently listed as the seventh son and the god of death — and his is the belief that proved most durable of all.
The record also captures the moment of fusion. With colonization, Old World lycanthropy grafted onto the native legend: the werewolf's curse settled on the seventh consecutive son of a family, said to transform on his thirteenth birthday. The slender native maned wolf lent the hybrid its silhouette, and the Luisón of the cemeteries became the lobizón of the countryside.
The Lore
Fear of the seventh-son curse ran deep enough to reshape law. Since the nineteenth century, Argentina's president has stood godparent to the seventh son of a married couple — a custom that grew from the old dread of transformation, formalized by Juan Domingo Perón's Decree No. 848 of 1973, which attached educational scholarships to the sponsorship while clarifying it conferred no special rights.
In modern Paraguay the Luisón survives as the country's signature night terror, told at wakes and on dark roads, its identity split between the old corpse-eating god and the transforming man of werewolf lore. Among the seven monstrous brothers, scholars note, these figures endure in rural belief to the present day even as the rest of the old pantheon fades — and none endures more stubbornly than the seventh.
