Rasputin is a Warmind built to defend Earth during the Collapse. He is the only Warmind known to have faced The Darkness and survived. He protects something deep below Old Russia that the Fallen House of Devils desire to retrieve. After a mission by a Guardian, he also began connecting to AI that were formerly controlled by other Warminds across the Solar System.
In The Buried City, the player's Ghost mentions that "He's everywhere now" at the end of the mission while analyzing a machine.
After the Fallen House of Devils reactivated SIVA, Lord Saladin hinted that the Vanguard didn't know Rasputin's true intentions, revealing that Rasputin had attempted to prevent the Iron Lords from reactivating SIVA, killing around 100 Iron Lords, trying to prevent them from releasing the evil.
Rasputin, along with Nokris and Xol awakened a few months after the Red War. Xol launches an assault on the Warmind, but failed in his attempt. Rasputin, along with the Young Wolf and assistance from Ana Bray defeated Xol using an upgraded version of the Valkyrie. When Xol was defeated, Rasputin granted an audience to the Young Wolf, Bray, and Zavala. There, he declared that he would indeed protect humanity, but on his own terms. fuack youo
