They are all Rasputin. But they are different aspects of his “mind” and “personality”. In order to survive The Collapse, he spread himself across different systems and different planets. We have been working all this time to try to reunite all of his functions. Now imagine that the part of Rasputin that was in the Cosmodrome was part that didn’t have access to any [i]moral[/i] subroutines. So you wind up with a “Rasputin” that behaves like a sociopath or an angry toddler. So when the Iron Lords try to take SIVA, he just ruthlessly kills them. Just like he did the Vanguard team that tried to contact him and they later “found pieces spread across the Cosmodrome” . What changed was the fifth mission in vanilla D1. [i]The Lost Array.[/i] The antennae we activated and defended from the Hive allowed Rasputin that was in The Cosmodrome to start communicating with the fragments on Mars. Rasputin’s behavior changed almost immediately. He started turning to us for help instead of seeing Guardians as another adversary. Both because he was more completely integrated, and Guardians were showing themselves to be allies in protecting humanity and not the warlords and power seekers the Chosen were prior to The Iron Lords. In Warmind the largest and most primary part of Rasputin comes back on line..,and now we have a fully awake and fully integrated Rasputin. [i]For The first time Rasputin actually **speaks** rather than trying to indirectly communicate with music and poetry.[/i] Now we see a more [i]mature[/i] and [i]relational[/i] Rasputin. Who has all his faculties now. But has clearly transcended his initial programming. On of the reasons why Rasputin did what he did was that he realized during The Collapse that conventional victory was impossible. So he basically did the equivalent of calling in an air strike on his own position as the system was being overrun. Allowing disaster, but staving off extinction. To allow the nature of the fight to change: The Traveller’s intervention; the creation of Guardians, and time for Rasputin himself to evolve. That process is now complete and Rasputin’s ready to [i]ally[/i] himself with The Traveller and the Vanguard in the defense of Humanity. But making it clear that he does not [i]serve [/i] either of them. [i]”I have no equal.”[/i]

Honestly, this is what pissed me off most about Warmind. Not Ana Bray coming back from the dead. Not Nokris having no explaination in the story. Not Nokris and Xol being incredibly easy. What pisses me off it how they completely retconned and changed Rasputin. The story pre-Warmind was that humanity had several Warminds, with Rasputin being the Warmind of Earth. The story now is that Rasputin has only been the only Warmind and all of the other “Warminds” were Subminds. The thing is, this makes absolutely no sense with everything that we’ve known. Why is it that Rasputin, a Russian speaking AI with a Russian name, LIVES ON MARS INSTEAD OF RUSSIA!? And in the Sleeper Simulant quest in Destiny 1, the Mars Warsat was referenced under Charlemagne instead of Rasputin. Bungie attempted to pass off this retcon as simply having bad information, and it failed horribly. But it gets worse. Remember the Last Array Mission? Apparently there was no point to that since Rasputin was on all of the other worlds already, if we go by the new Bungie story. In the Grimoire, orbital strikes on Mars were attributed to us opening up the Array. Guess not, since Rasputin was not just already on Mars, but has his main facility on Mars. The most disturbing thing about this is Bungie’s philosophy for adding new story to the game. Instead of adapting new ideas to fit the existing story, they are jamming their new ideas into the existing story regardless of the coherency of it. I’ve thought of tons of ways that the same story in Warmind could have gone down in a way that fits in with what has been established, but Bungie doesn’t seem to care about that. Their way of doing things as they are now can’t sustain itself. People care about Destiny and it’s story too much for Bungie to continue disregarding and mishandling it like they do.

Did you play the campaign? Its pretty clear to me, they didn't make it very complicated.

All that is folklore

This is what has been pieced together. Back before us, the Warminds were a legend, not really a myth because people knew without a doubt they existed but they kinda got the King Arthur treatment. It wasn't really till we came along that things changed, we interacted with a Warmind, one of many we thought. But turns out it was only a fragment of a Warmind. It wasn't until we got the Comms Array back online that part of Rasputin was able to reconnect to the whole. The Whole of course was the main systems for Rasputin which was still dormant on Mars. But once the fragments from Earth reconnected it powered back up. However from the way it looks it was content to just ignore us and study the threat at it's front doorstep, Xol and Nokris. It wasn't until the Traveler was awakened that things changed, Xol was roused from it's slumber and Rasputin had to take a more aggressive posture with the Hive on Mars. How he was going to battle them, is not known could be a shit ton of Frames stored somewhere or he figured rain enough Warsats down he would eventually get one of the big baddies. Heck it could have been as simple as the Wasats were a signal flare to bring us dumb Guardians in, without actually asking for help. While he knew something had to be done about the Hive. He was also around during the Collapse and knows there is a threat out there even more dangerous. For him to reveal and deplete what is surely limited resources now would not be the optimal usage of said recourses. So he is content to let us do the heavy lifting and to provide what support he can spare without revealing his true power. How did Zavala he get in, to think Ana Bray was the only one who had knowledge on Rasputin is a tad naive. The amount of reports that Zavala had access to would probably stun a water buffalo in its tracks. And being the person he was, he wouldn't trust anyone else when it came to Rasputin. Plus like I said this could have been what Rasputin wanted, who better to deal with the cockroaches than the Leader of the Vanguard. With him in charge he could keep Rasputin a secret, but still eliminate a threat to Earth.

The only time Charlemagne was mentioned, was during a developer interview before Destiny was even released. The lore community believed Charlemagne to be a Warmind that the community wrote it into their lore. As for Rasputin being on Mars, he is a computer AI he can go where ever there is enough space for him to download into. Hasn’t anyone actually seen or read science fiction where A.I.s take control of other computers?
