Hey guys and girls.
I've noticed that many of the systems that are populated with ruins are, for the most part until I finish my analysis, filled with at least 1 planet that is 100% Sulphur. (Edit; planets with sulfur are not unusual, but the frequency in which they show in systems populated by guardian ruins is not normal - I've done plenty of exploring in this game to notice something is out of place here).
I'll update one of my pages/threads soon when I have more time over this weekend, but for now I'm working on this hypothesis:
The Guardians used Biological Warfare as their main weapon - usually against themselves. However, from the scant data we have from the Codex entries, it was mentioned that this wasn't effective against the AI's (for obvious reasons).
So, if the Guardians did eventually have a war with the AIs, then what would machines use against their progenitors who had mastered the art of biological warfare and medicine?
Chemical Weapons. Chemical Warfare.
Mustard Gas - Sulfur being the prime ingredient.
The AIs would not have been in short supply of Sulfur, considering it is pretty common on many landable planets - and this would have totally circumvented the Guardians greatest weapon and defence when it came to biology.
I would hypothesis this: the AIs completely bombarded each of the Guardians colonised worlds with Sulfur. They used so much Sulfur, it turned the atmosphere completely toxic with the substance.
This was total genocide of an entire race on an intergalactic scale.
I will report more of my findings soon once I've been and scanned all the planets in each of the ruin systems - so far, it is looking more likely in each system I analyze, that this could be the case.
