THINK ABOUTIT’S ALIEN TYPE SUMMARY – The Invisibles

Of all the entries in the Book of Alien Races, “The Invisibles” may be the most honestly named — and the least documented: a type described almost entirely by what cannot be seen, tracked by radar but never by eye, identified only by a sour smell in the air, a smudge at a windowpane, and a dog that won’t stop barking at nothing.

Name: The Invisibles

AKA: Not reported in any source

Location – Home System: Constellation Mensa (per source; no planet or system named)

Distance from Earth: Not reported in any source

Attitude: Not reported in any source

Motives: Reported in the source as unknown

Physical Appearance: The source states only that this type is “almost completely invisible to the naked eye.” No further description is given.

Average Height: Not reported in any source
Average Weight: Not reported in any source
Body Temperature: Not reported in any source
Pulse/Respiration: Not reported in any source
Blood Pressure: Not reported in any source
Life Expectancy: Not reported in any source
Hair: Not reported in any source
Skin: Not reported in any source
Eyes: Not reported in any source
Sex: Not reported in any source

Other Physical Information: Not reported in any source

Special Traits and Abilities: Not reported in any source, beyond the near-invisibility described above

Communication Type: Not reported in any source

Origin: Constellation Mensa; no further detail on planet, civilization, or point of origin appears in the source

Life Form Type: Not reported in any source

Subspecies: Not reported in any source

Most Common Species: Not reported in any source

Level of Species: Not reported in any source

Habits: Not reported in any source

Transportation Type: The source states that associated craft can be tracked by military radar, while the beings themselves cannot. No further description of the craft is given.

Witnesses Reports: No named, dated, or located witness account appears in the source material. The source instead offers three general detection signs: (1) a sour smell reported in their presence, (2) a smudge-like reflection visible on windows or CCTV, and (3) dogs barking without apparent cause. No specific encounter, witness, date, or location should be attributed to this entity.

Special Features/Characteristics: The source lists three detection signs: a sour smell reported in the entity’s presence, a “smudged,” ghost-like figure occasionally visible near windows or captured on CCTV, and dogs barking without apparent cause when the entities are said to be present (a behavior the source also links to reported “reptilian” encounters). Both the Russian and U.S. militaries reportedly developed radar technology capable of tracking associated craft, though not the beings directly. The source states this type has been reported near high-security locations.

Summary/Description: A minimally documented type whose entire defining trait, per the source, is near-total invisibility to the naked eye. Beyond that single characteristic, a constellation of origin, an unstated purpose, and three secondhand detection signs — sour smell, window smudges, agitated dogs — are all the source material provides.

DETAILED REPORT

“The Invisibles” is one of the sparsest entries in “The Book – Alien Races,” a self-published compilation attributed to Dante Santori that circulates online with no independently verifiable chain of custody. Where many entries in the same compilation include claimed histories, contact dates, and named locations, this entry consists of a short block of descriptive text and little else.

The core claim is straightforward: a type of entity that is “almost completely invisible to the naked eye,” reportedly detectable only indirectly. The source states that both Russian and American military programs are said to have developed radar technology capable of tracking the type’s craft, but not the entities themselves — a claim that, like the rest of the compilation, is presented without citation, document, or named source within any government or military body.

Beyond that, the source offers three loosely described indicators associated with the type’s presence: a sour smell reported in their vicinity; a “smudged,” ghost-like figure sometimes visible near windows or on CCTV footage; and unexplained barking from dogs, which the source also associates with reported “reptilian” entities elsewhere in the same compilation. A general association with sightings near high-security facilities is also noted. None of these indicators are tied to a specific date, location, or named witness in the available source text.

The entry names the entities’ point of origin as the constellation Mensa, offering no further detail — no planet, no civilization name, no travel method beyond the radar-detectable craft already mentioned. The type’s motives are explicitly described in the source as unknown.

No biometric data, no named military program, no dated encounter, and no specific witness account appear anywhere in the traceable source material. Any prior version of this page presenting such details was not reflecting the source — it was inventing content the source never provided.

RESEARCHER’S NOTES

The Invisibles — Constellation Mensa and the Limits of a Single-Paragraph Source

Classification and Source Correction: Prior versions of this entry attributed detailed biometric ranges, a named task force, and a specific 2001 witness encounter to this type. None of that content traces to the “Book of Alien Races” source or any other identifiable document. The corrected entry above reflects only the handful of claims that actually appear in the source text.
Source Chain Assessment: The ultimate source is a self-published, undated compilation of alleged alien types with no identified author, no cited government or military documentation, and no independent corroboration. It functions as folklore-adjacent content rather than an evidentiary record, and this entry should be read accordingly — as a summary of a claim, not a summary of an event.
Pattern Context: The “invisible but radar-trackable” motif recurs informally across UFO folklore more broadly, often paired with secondary indicators like electronic interference or animal reactions — dogs, in this case — standing in for direct observation. This entry’s dog-barking indicator is explicitly shared with the compilation’s separate “reptilian” entries, suggesting the source itself was not treating the indicator as type-specific.
Evidentiary Weight: There is no physical evidence, photograph, radar record, or named military statement associated with this type in the available source material. Every claim here is a secondhand assertion within an unsourced compilation, and the entry should be weighted accordingly — as an unverified folklore entry rather than a documented case.
Geographic and Naming Context: Mensa itself is a real, modern constellation — cataloged in the 1750s by Nicolas-Louis de Lacaille and named for South Africa’s Table Mountain. It is the faintest constellation visible from Earth, containing no stars brighter than fifth magnitude. That obscurity likely explains its selection as an “invisible” species’ point of origin in the lore, though the source draws no explicit connection between the constellation’s astronomical faintness and the entities’ claimed invisibility.

Stripped of its invented additions, “The Invisibles” is exactly what its single-paragraph source describes and nothing more: an unverified folklore type defined by absence — no confirmed sighting, no named witness, no physical trace, only a claim of undetectability and a scattering of secondhand indicators. The record here is honest about how little there is to record.

The source describes the type as “almost completely invisible to the naked eye,” tracked by radar on their ships but never directly observed. (Book of Alien Races, via gigantiidacia.wordpress.com)

REMOVED CLAIMS (Archived for Reference)

The following details have circulated in connection with this entity — including in earlier drafts of this page — but do not appear in the actual source material. They are archived here rather than deleted, in case a verifiable source for any of them is identified later. None of the items below should be treated as documented until that happens.

Average Height: ~2 meters (~6’6″) — circulating lore, no source found
Hair: smooth, hairless surface — circulating lore, no source found
Skin: translucent/shimmering, refractive under light — circulating lore, no source found
Eyes: pupil-less, pearlescent orbs — circulating lore, no source found
Physical solidity: claimed to leave footprints in soft ground or snow despite invisibility — circulating lore, no source found
Special Traits: nocturnal activity pattern; light-bending cloaking ability — circulating lore, no source found
Communication Type: speculated telepathic or high-frequency resonance, inferred only from dog reactions — no direct evidence in source
Most Common Species: “Mensa-Prime collective” designation — no basis found beyond secondary retellings
Level of Species: Kardashev Type II classification — unverified, likely an invented flourish
Cross-contaminated details: age, a species-war history, and a 2001 Italian Alps encounter previously attached to this entity actually belong to a different entity (Dorsay) in the same source compilation and should not be attributed here
