The Sirians — the Katayy of Sirius A and the varied populations of Sirius B, per contactee Alex Collier.
THINK ABOUTIT’S ALIEN TYPE SUMMARY
SIRIANS
In the Think About It Alien Database, the Sirians are documented across a substantial body of real, checkable ufology source material — chiefly contactee Alex Collier’s claims about the Katayy of Sirius A and the varied populations of Sirius B, and the broader “Ashtar Collective”/Dulce-Furnace Creek base lore already documented elsewhere in this archive’s Rigelians entry. This entry preserves that genuine source material, adds important academic context on the disputed Dogon/Sirius B connection, and removes an invented biometric panel and 2026 storyline that appear in none of it.
Name: Sirians
AKA: The Katayy (Sirius A population, per Alex Collier); the Nommos (aquatic beings associated with Dogon tradition); Men in Black (MIB) entities, associated with Sirius B in this source material.
Location – Home System: Sirius (Alpha Canis Majoris), a real binary star system consisting of Sirius A and the white dwarf Sirius B (discovered 1862). A third star, “Sirius C,” is an unconfirmed and scientifically disputed claim within the source material itself, reportedly observed only once, in 1929.
Distance from Earth: Approximately 8.6 light years — a real, confirmed astronomical figure.
Attitude: Per Alex Collier: the Katayy of Sirius A are considered benevolent, motivated by a sense of responsibility since Sirius B was originally colonized from Sirius A. Sirius B is associated in the same source material with more negative, control-oriented factions, including the alleged origin of Men in Black entities.
Motives: Per the source material, the Katayy work to assist human evolution by altering Earth’s “bio-magnetic energy grid.” Sirius B factions are separately described as having provided exotic time/interdimensional travel technology to human government programs, including the Philadelphia Experiment and Montauk Project narratives, per contactee Preston Nichols and Alex Collier.
Physical Appearance: Per Collier: Sirius A’s Katayy are of Lyran/Vegan descent, predominantly red-skinned with some variation. Sirius B populations are described as red, beige, grey, or black-skinned humans with cat-like eyes, alongside separately described reptilian and aquatic beings. Sirians who settled permanently on Earth are described as having lightened in skin tone over time through interbreeding with Lyrans and adaptation to Earth’s climate.
- Average Height: Undocumented as a specific figure in the source material.
- Average Weight: Undocumented.
- Body Temperature: Undocumented.
- Pulse/Respiration: Undocumented.
- Blood Pressure: Undocumented.
- Life Expectancy: Undocumented as a specific figure.
- Hair: Undocumented.
- Skin: Red, beige, grey, or black, varying by faction, per Collier (see Physical Appearance above).
- Eyes: Cat-like, per Collier’s description of Sirius B populations.
- Sex: Undocumented as a specific detail beyond general humanoid description.
Other Physical Information: Sirius B-associated Men in Black entities are described in the source material as parahuman, cybernated, or “chameleon-like” in appearance.
Special Traits and Abilities: “Etheric implants” — described as non-physical, energetic devices functioning as a remote-control interface — are a central and consistently documented claim across this source material, said to have originated as a benevolent Sirian tool for accelerating spiritual development before being adapted for more controlling purposes.
Communication Type: Undocumented as a specific method beyond general telepathic claims common across this genre.
Origin: Described in the source material as originally of Lyran/Vegan descent, having settled Sirius following what this lore calls the “Lyran wars.”
Life Form Type: Humanoid (multiple skin-tone variants), with separately described reptilian and aquatic populations also associated with the Sirius system in this source material.
Subspecies: The Katayy (Sirius A); unnamed red-, beige-, grey-, and black-skinned human populations, reptilian beings, and aquatic beings (Sirius B), per Collier.
Most Common Species: Undocumented as a formal designation.
Level of Species: Undocumented; no numbered ranking system appears anywhere in the source material.
Habits: Per the source material: involvement with human secret societies and “Illuminated” orders; a long-documented association between cetaceans (dolphins, porpoises, whales) and Sirian consciousness in wider galactic lore, alongside an unconfirmed and disputed claim of a similar cetacean-inhabited planet at Alnitak in Orion’s belt.
Transportation Type: Undocumented as a specific craft description in the source material reviewed.
Witnesses Reports: Alex Collier, an American contactee claiming ongoing contact with beings from Andromeda who has described the Sirian system at length; the Dogon people of Mali, whose claimed traditional knowledge of Sirius B is the subject of significant, unresolved academic controversy (see Detailed Report); Robert Temple, author of The Sirius Mystery (1976), who popularized the Dogon/Nommos connection.
Special Features/Characteristics: The “Ashtar” or “Astarte” Collective — a described alliance of humanoid and other species that, per this source material, experienced a rift between factions aligned with a “Federation” (associated with a base at Furnace Creek, California) and factions aligned with an “Orion-Draconian Empire” (associated with a base at Dulce, New Mexico), with additional shared facilities described beneath Paradox, Nevada; Dugway, Utah; and the Denver International Airport.
Summary/Description: The Sirians, as documented in this source material, are a Lyran/Vegan-descended people who settled the Sirius system, later dividing into the benevolent Katayy of Sirius A and a more varied, sometimes negatively framed set of populations in Sirius B, including the alleged origin of Men in Black entities. They are described as having played a role in human history via genetic involvement, the Nommos/Dogon connection, and the invention of “etheric implants,” and as one faction in a described rift within the broader “Ashtar Collective.” The claim that the Dogon people independently possessed advanced knowledge of Sirius B prior to Western contact — central to this source material’s Nommos narrative — is not settled history; it is the subject of substantial, still-unresolved academic dispute (see Detailed Report).
Source: Alex Collier’s contactee material, as compiled on Exopaedia (exopaedia.org, entries for “Sirius” and “Katayy”) and Truth Control forum archives; Robert Temple, The Sirius Mystery (1976); Marcel Griaule and Germaine Dieterlen’s original Dogon fieldwork (1930s–1940s); Walter van Beek’s 1991 follow-up field study; the broader “Ashtar Collective”/Branton-lineage material already documented in this archive’s Rigelians entry.
Related Cases: The Rigelians, documented separately in this archive, share the same “Ashtar Collective”/Dulce-Furnace Creek base lore lineage. The Dogon/Sirius B knowledge controversy is a documented academic dispute independent of this archive.
DETAILED REPORT
The Sirians entry rests on an unusually large body of real, named, checkable source material for this genre — chiefly the claims of contactee Alex Collier, compiled across Exopaedia’s “Sirius” and “Katayy” entries and elsewhere, describing a benevolent Katayy population on Sirius A and a more varied, sometimes conflict-associated set of populations on Sirius B, including the alleged origin of Men in Black entities. This material also documents “etheric implants” as a central, recurring claim: energetic, non-physical devices originally intended for benevolent spiritual acceleration, later adapted by “negative forces” for control. The broader “Ashtar Collective” rift, with factions based at Furnace Creek, California and Dulce, New Mexico, and shared facilities at Paradox, Nevada, Dugway, Utah, and the Denver International Airport, is the same lore lineage already documented in this archive’s Rigelians entry.
The Nommos/Dogon connection deserves particular care, since it involves a real, living culture and a genuine, still-unresolved academic controversy — not simply a matter of checking a ufology source against itself. Robert Temple’s 1976 book The Sirius Mystery popularized the claim that the Dogon people of Mali possessed traditional astronomical knowledge of Sirius B — a companion star invisible to the naked eye, discovered by Western astronomers only in 1862 — based on 1930s–1940s fieldwork by French anthropologists Marcel Griaule and Germaine Dieterlen. This claim has been substantially challenged since: in 1991, anthropologist Walter van Beek conducted follow-up fieldwork among the Dogon specifically to verify this knowledge and found no evidence that his informants considered Sirius a double star or attached particular significance to it at all. Van Beek and others have proposed that a 1893 French astronomical expedition to the region, which spent five weeks observing a solar eclipse, may have introduced this information well before Griaule’s fieldwork. The dispute remains genuinely unresolved in academic circles — some scholars have defended Griaule’s original data against van Beek’s critique — and this entry presents it as an open controversy rather than settled evidence either for or against extraterrestrial contact.
Nothing in the source material reviewed for this entry — Collier’s testimony, the Ashtar Collective lore, or the Dogon/Nommos material — includes a formal biometric panel, a numbered “Level XV” species classification, or any 2026-specific narrative describing an “activation” of Earth’s bio-magnetic grid or a public exposure of Sirius B/”Serpent Cult” alliances. These do not appear anywhere in the documented source material and have no independent support.
RESEARCHER’S NOTES
Sirians — A Well-Sourced Entry, With One Real Academic Controversy Worth Naming
- This entry rests on real, named, traceable source material: Alex Collier’s contactee claims, compiled and cross-referenced on Exopaedia, form the backbone of the Katayy/Sirius B description — this is not anonymous or invented content.
- The Dogon/Sirius B connection is not settled fact and should not be presented as such: Walter van Beek’s 1991 field study found no evidence for the astronomical knowledge Robert Temple’s 1976 book relied on, and a plausible mundane explanation (a documented 1893 French astronomical expedition to the region) exists. This is a real, still-debated academic controversy involving a living culture, not a settled historical fact.
- The Ashtar Collective/Dulce/Furnace Creek material is shared lore, not unique to this entry: it traces to the same Branton-lineage source documented in this archive’s Rigelians entry, and is presented here with that cross-reference intact.
- The biometric panel and “Level XV” classification were invented additions: no source consulted for this entry provides specific height, weight, or numbered-ranking data for Sirians.
- The 2026 “grid re-activation” and “Serpent Cult exposure” narrative is invented outright: it does not appear in Collier’s material, the Ashtar Collective lore, or any Dogon-related source.
The honest state of this entry is that the Sirians are among the more thoroughly and traceably sourced entities in this archive, resting on a named contactee’s compiled claims and a genuinely documented (if long-running and unresolved) academic dispute about the Dogon people’s astronomical knowledge. That dispute deserves to be presented as exactly that — a real controversy, not evidence settled in either direction — rather than folded into a confident narrative about ancient alien contact.
No verified period-accurate quote unites this entry’s several source strands; Collier’s own claims are paraphrased above rather than quoted at length, and this entry does not invent an attributed quote to fill the slot.
