The Third Moon's Relationship To The Xenomorph?

Calpamos is a gas giant in the Zeta II Reticuli binary star system. Orbiting Calpamos are three small moons, Acheron LV-426, LV-223 and another that remains thus far unnamed. LV-426, a primordial moon, is known to be the resting place of a derelict Juggernaut together with a cache of thousands of Ovomorphs (Xenomorph Eggs). LV-223, a temperate moon, is the site of an array of deserted facilities of Engineer origin, and the wreckage remains of the USCSS Prometheus and an Engineer Juggernaut. The third, unnamed moon remains a mystery, though there is high probability it will likely house some Engineer facility related to both the Black Pathogen bioweapon found on LV-223 and the hordes of Ovomorphs located on LV-426.

In both Prometheus and Alien: Covenant David used Dr. Elizabeth Shaw's reproductive organs, both inadvertently and directly to realize the genetic code hidden within the Black Pathogen - the Xenomorph. The trilobite organism Shaw removed from her womb was a forebearer of the Facehuggers gestating within the Ovomorphs David later cultivated from her ovaries. As such one would imagine that Trilobites and Ovomorphs would have also resulted had the Engineers experimented in the same way on the females of their race. The cache of thousands of Ovomorphs on Acheron LV-426 would suggest that such experiments have indeed taken place prior to the death of the pilot of the derelict Juggernaut, and prior to the events that claimed the lives of all but one of the Engineers stationed on LV-223, approximately 2000 years ago.

When comparing the mural found in the ampule room on LV-223 with H. R. Giger's art an unforeseen possibility presents itself. Rather than just showing the life cycle of the Deacon, and by extension the Xenomorph, the mural could also be showing the source of the Xenomorph eggs. Many of Giger's artworks feature women in a similarly bound position, usually portraying the act of consummation. You will notice a macabre parallel between these paintings and the mural, with the central figure's abdomen, opened, with mirrored fetal figures separating it and the depictions of Xenomorph parasites implanting hosts with their embryos. The mural could also be depicting an Engineer females body being used to create Ovomorphs.

This is what I believe may be on the third moon of Calpamos, a vast facility reminiscent of Giger's paintings in which chosen female Engineers are sacrificed, their bodies used the creation of Ovomorphs using samples of the Black pathogen cultivated on LV-223. It could be that the derelict Juggernaut on LV-426 was transported said Ovomorphs from this third moon when it was forced to land, its pilot having fallen foul to its cargo. Although it is possible the pilot of the derelict may have visited LV-223 beforehand. It is known that around the same time that the derelicts pilot died on LV-426, the Engineers stationed on LV-223 suffered an "outbreak". It is presumed this outbreak was the Black Pathogen, but there is actually no evidence to support this as the ampules containing the deadly substance remained undisturbed until Dr. Shaw and her team breached the chamber in which they were stored. All but one of the Engineers died from "Burster" like wounds, which suggests that rather than an outbreak of the Black Pathogen, one or more Xenomorphs were responsible for their deaths, and with no evidence of any female Engineers on LV-223 it is highly unlikely that a Xenomorph was formed from exposure to the Black Pathogen. With the derelict being the only known source of Xenomorphs in the immediate vicinity of LV-223, this would suggest that the outbreak came from the derelict Juggernaut and that its pilot was responsible.

This would mean that the pilot of the derelict Juggernaut on Acheron LV-426 was aware of the plans of the Engineers stationed on LV-223 to use the Black Pathogen on Earth, and that he used his cargo of Ovomorphs to stop them, putting themselves at risk doing so, before being forced to land on LV-426 and recording their last message, warning any and all away from the three moons. This would fit in with Ridley Scott's comments in the commentary for the 2003 directors cut of Alien, in which he states his belief that the pilot of the derelict Juggernaut was benevolent.
