The most controversial 'whistleblower'/'contactee' reports concern an off-world 'master Reptilian race' described as the Draco-Reptilians who are claimed to originate from the Alpha Draconis star system which is 215 light years distant and was formerly the pole star. According to Alex Collier, the Draconians or Dracos have two main castes, the first of which is a warrior caste that are in the 7-8 foot range, who are apparently feared throughout the galaxy for their fighting abilities. The second caste are a 'royal line' of Draco Reptilians that he describes as 'Ciakars' which, because of their alleged size, psychic ability and alleged wings, might be confused as the proverbial Dragon if Collier is correct:

"The Draconians are a very large reptilian race, otherwise known as "the Dracs". There is royal line of the reptilian race called the Ciakar. They range from 14 to 22 feet tall and can weigh up to 1,800 pounds. They do have winged appendages and they are awesome beings. They're extremely clairvoyant and extremely clever, and they can also be extremely sinister.".

Collier claims that according to the Draconian world view, they were the first intelligent species in the galaxy and seeded many worlds with their biological off-spring. The Draco Reptilians therefore see themselves as the natural rulers of Reptilian 'controlled' worlds such as Earth, and view humans as an inferior species. The Draconians are interested in harvesting the Earth's resources while ensuring that these resources are efficiently exploited.

There appears to be a strict hierarchy involving the Draco-Reptilians and other extraterrestrial races so far described in this group. According to Thomas Castello, Reptilians from Alpha Draconis, the 'Dracos', are in command of the Earth based Reptilians. Earth based Reptilians are in turn in command of the 'tall Grays', who are in command of the short Grays. Interestingly, Castello also describes the Draconian ruling caste as Ciakars who are winged and therefore could be easily confused as dragons. Jefferson Souza, a Brazilian UFO researcher confirms the existence of a hierarchy involving the Grays and a Master Reptilian race.

All of the extraterrestrial races described above appear to have a number of interlocking agreements between them that have a common interface in the agreements between U.S. national security agencies and the Grays. The Draconians form the (hidden) apex of the military-industrial-extraterrestrial complex (MIEC) that controls information and technology related to the extraterrestrial presence. The Draconians appear to be very active in controlling human elites, institutions and financial systems; promoting militarism; creating a climate of scarcity, struggle and insecurity; harvesting humans and manipulating Grays and other Reptilian races. Draconian activities contribute to global problems such as concentrated wealth, corrupt elites and institutions, ethnic/religious violence, human rights abuses, a culture of violence and terrorism, and the drug trade and organized crime.
