According to Thomas Castello, a former Dulce base security officer -- this particular under-world city is a highly secret base operated by humans as well as reptilian aliens and their worker cast, the commonly encountered grays.
It is here, apparently, that a multitude of experimentation projects are carried out. Primarily genetic experiments on kidnapped men, women, and children.

Philip Schneider claimed to be a former US Government Geologist and Engineer, who was involved in producing the underground explosions which were required to facilitate the building of various underground military bases, as well as submarine bases for the United States Government.
He claimed to be one of only three people who survived the infamous Alien/Human War at Dulce and Los Alamos, where 66 Government Agents and Workers supposedly lost their lives in August of 1979.
Dulce Base is an alleged joint human and alien underground facility under Archuleta Mesa on the Colorado-New Mexico border near the town of Dulce, New Mexico, in the United States. Claims of alien activity there first arose from Albuquerque businessman Paul Bennewitz.

REPTILIANS AND THE ROYAL BLOODLINE - David Icke
David Icke explains his infamous theory why 'Queen IS a shape-shifting reptile'
The former BBC Grandstand presenter, who famously came out as a major conspiracy theorist during an interview with the late Sir Terry Wogan in 1991, was interviewed for a YouTube video shown by channel New World Order TV.
In it, he cemented his claims that the British royal family are descended from a reptilian blood line.
Icke subscribes to the Illuminati conspiracy theory that a secret society made up of the royals, political and business leaders actually pulls the strings of world, seemingly democratic governments, from behind the scenes.

ONE OF THESE SPECIES HAS BEEN DESCRIBED AS A “HUMANOID REPTILE” BECAUSE OF ITS APPEARANCE WITH TERRESTRIAL REPTILIAN SPECIES. ABOUT TEN SPECIMENS HAVE BEEN STUDIED BY THE INKARI – CUSCO INSTITUTE BETWEEN 2017 AND 2018.
The following anatomical features are noted:
The three fingered hands and feet are not distortions listed in the modern medical literature, in the event of possible congenital diseases.
The skeletons of the hands and feet are anthropometrically correlated.
Macro-cephalic skulls show no evidence of artificial mechanical pressure, to produce this elongation.
This species does not have any dentition or eye flag.
No hair at all.
The neck may be retractile.
The body have neither mammary glands nor umbilical scar to attach this species to mammals.
The number of ribs is variable following specimens: from 8 to 11.
The specimens studied by the Inkari – Cusco Institute team measure between 47 cm and 60.50 cm. This species has an oval-shapped macro-cephalic head lengthened towards the back, larger at the front. Its front part is ended with a pointed form. The upper part of the skull has three ridges or “crests”, without any hair. Neither nasal septum nor ear flag are observable, but X-rays showed a middle ear (internal).
