The event Alejandra Silvain describes is placed at Marindia in Uruguay in January 1969, when she was five years old. She says she was woken at night by her mother, who was in a trance-like state, and led out to a forest where the family stood paralysed beneath a hovering strobe-lit saucer. She was drawn up a beam of light and placed on an operating table under bluish light. There she describes a painful procedure of genetic extraction done with metal rods, and insertions through her nose, carried out by greys working under the direction of reptilian beings. A feminine reptilian was said to fertilise the extracted material. She was promised psychic gifts. Then a second craft appeared, a mothership she attributes to a Galactic Confederation, and luminous blond beings apologised to her, saying the reptilians had broken a pact.
What is on the record
One telling, one channel, one video. The archive resolves four claimants: Silvain, her mother, Rodolfo and Julio César Silvain. All four names arrive through that same single source, and the three family members carry no separate accounts of their own here. What the archive holds is a childhood memory recounted in adulthood, and the entry marks both conscious recall and hypnotic regression, so at least part of the account rests on a method whose reliability is widely questioned. There is no physical evidence, no contemporary report and no document of any class in the file.
Why it sits where it does
The case grades L3 on the number of people named as present, not on independent accounts arriving separately. Everything reaches the archive through one telling, which is a weaker footing than the tier usually implies. What happened in the forest at Marindia, and aboard whatever hung over it, is not resolved here.
