I'm gonna give my evidence on why I think SIVA may be a variation of the vex. 1st, During the reveal stream today, Bungie said that the plague was literally eating away at the ground and planet. We know the vex do this like they did to Mercury. 2nd, we know golden age scientists studied some vex ruins. Could t be possible that they used some sort of vex robot as a basis for the SIVA program? 3rd, the enemy mechanics. I saw how the splicer fallen acted and it shocked me. Solar weapons. Void shields. Even the fact they're building things. It's very similar to how the vex operate. 4th, we know SIVA betrayed humanity and the iron lords died trying seal it away. I get the feeling they knew something we didn't. Why would the iron lords attack SIVA and not something like the hive or the fallen? 5th, Rasputin. He's been dodging us at every turn, trying to bring stuff back online. He crippled the traveler. In fact in the mission where the hive tried to kill him, he had multiple pictures of the ex and the planets they were currently on, Mars and Venus. Why? Is he considered some sort of friend to the vex? Maybe a god? In the dust palace strike, we see the vex worshipping the machine that was holding Rasputin. But he's a Warmind. And so was SIVA. Maybe that's why the vex "like" Rasputin NervousHeroC4 made a interesting point! [quote]They also mentioned that SIVA was created during the golden age. What if SIVA was mankind a attempt to copy the vex? Just gonna let that sit for a moment.[/quote] Rh0deykl [quote]I believe that SIVA was an attempt by mankind to create a powerful AI that can stand up to the vex. Another theory I have is that SIVA was an attempt to create a super-intelligent AI to devise a plan to take back the universe. So, all in all, it might be based off the vex, but personally, i believe that the vex were just the seed of the idea for SIVA.[/quote] That's all I have. If you have something to contribute please don't hesitate to say so!
