I must mention at the start this is not entirely my theory. This was a theory discussed by both me and a fellow lore enthusiast TKfromthe90s. He also should receive credit for this theory.
Firstly, we must start at the beginning. At the Book of Sorrows. Specifically, Chapter XLII: <>|<>|<>. In this chapter, we see a confrontation between Oryx and Quria, Blade Transform. We can also see the thought processes of Quria, in directives. This is the thought process we would most likely assume for the Vex, as they are machines after all. However, one directive that caught our attention was this line, made by Quria:
It was from this one line that our theory began to unfold, as this layout that the words were in very closely resembles that of the command directive set for SIVA, which as we know is:
We theorised that perhaps, based on the research the Ishtar team carried out on them, Clovis Bray somehow managed to code the SIVA nanites to use a similar form of self replication to that of the Vex, as we know that the Vex have the capabilities of replicating themselves, as well as construct massive structures incredibly fast (this can be seen most clearly on planets such as Nessus, Venus, and certainly Mercury). However, our sole focus will be the structure based on Venus.
Now, we began struggling to find a link between the Ishtar Research team and Clovis Bray, other than simply being two scientific research laboratories, until, whilst scouring the grimoire, we found in the card “Ghost Fragment: Vex 3” on of the researchers stating:
DUANE-MCNAIDH: I wish I’d taken that job at Clovis.
This is were the majority of the theory is slightly speculative. We theorised that these researchers perhaps either shared or used their research to apply to Ishtar, or at least share the information. This occurred before the events unfolding in these cards (hence why the man in question is referring to the past), as then the researchers replicated their consciousnesses to enter the Vex network and so on.
However, we also believed that perhaps, from what we see in the Books of Sorrow, some of the Vex’s core programming has been adapted from the Hive, most importantly, this fight we see between Oryx and Quria. Just before Quria is ‘Taken’ by Oryx, he sends a transmission out across the Vex network, sharing his deductions of the Sword Logic. We know the Vex received this and understood it to some extend, and can see this influence through their “Throne Spaces”, most notably, the Vault of Glass,l which was likely based around this theory.
But, what if some of these subroutines of the Vex were, unintentionally, transferred into SIVA (again, speculation), through the code that it is programmed to run. This in turn would mean, by proxy, the Hive philosophy would also have some kind of influence over the subroutines of SIVA.
This influence can be seen in the Rise of Iron expansion, in which we encounter the “Archons Forge”, a place where fallen come to fight opponents, worship their new god, SIVA, and in turn, grow stronger through comabt , and the art of killing. As well as this, we also see the replication chamber where Aksis resides, yet another example of an area potentially based off the Hives “Throne Spaces”.
I would again like to thank my fellow lore enthusiast, and good friend, TKfromthe90s, for helping to create this wild theory.
Do feel free to ask questions, and I am sure both of us will be willing to answer them.
