Here is my theory: Thargoid interceptors and scouts are the product of the genetic engineering of the guardians. Or possibly their corrupted AI. For warfare.
why? Because in the logs Ram Tah mentions the guardians's prowess at bioengineering and there are no escape pods or pilots visible inside the interceptors.
FDEV PLEASE ACKNOWLEDGE IF I PREDICTED YOUR NARRATIVE!!!
Here is what it is in reality of Elite Universe.
The origin of Thargoids is still a mistery. They are more than 2 million years old. Much older than Guardians. Guardian AI was never corrupted. It become sentient at one point and decided to eliminate a threat to them (guardians) to establish their own civilization. And they did. And we just triggered them already. And many months or year latter (in whatever update) will see their reaction to our presence in the galaxy.
Thargoid interceptors and scouts are just biomechanical advanced machines - as an answer to Guardian strategy in war. Interceptor was created to scan everything in search of guardian tech and eliminate it. It was designed with idea to be damaged, but still be able to fight guardians military machines. That's why it have lightning strike after first heart is damaged and EMP to defect guardian machines offensive capabilities. However, thargons was never mentioned in Guardian - Thargoid conflict. Guardians defeated thargoids in this conflict and forced them to retreat.
My guess - thargons is their own adaptation against humans.
I noticed that some pilots in the thread are wondering why are they doing it.
Well, their motivation is pretty easy to explain. They seeded this whole region of space more than 3 thousands years ago. All they want now is their own space. How to determine which one of our space is actually theirs? Just look for ammonia world in the system. If system have such planet, there is 90% chance that thargoids marked it as a target.
What they think about us? Pretty much nothing. We can't do anything to them, we can't stop them. We can only win some time, and they are aware of it. They also use our weakness in society (Far God cult and others + Galnet).
Are they trying to eliminate us as a species? No they don't. In fact not even trying. They only want something that is theirs.
They will not touch SOL or any other important to Humanity systems. Cause they simply have no purpose to them or resources.
There is a chance however for SOL attack because of Aegis provocation on thargoids (Aegis core moved to SOL).
Overall the war is still not happened. It's just a local territorial conflict for now. And thargoids never put the whole system into crysis. They only trying to force system to retreat. With as less casualties as possible.
Are they good? No. Are we good? No.
Are we started this conflict? Yes.
Should you participate in this conflict? It's your call. But thargoids don't really care.
