Grigori Yefimovich Rasputin

Grigori Yefimovich Rasputin (1871-1916) was a Russian monk, who would make a serious impact on Earth and Mars alike.

Prior to Martian Dreams, Rasputin was visited by Raxachk in his dreams, compelling him to sabotage the space cannon into firing too early. Once on Mars, Raxachk lured Rasputin into a Dream Machine and took over his body, leaving Rasputin in a nightmare of his own assassination. He also told the Avatar that much in Argyre, once Raxachk had fled his body.

After his return to Earth, his nightmare would come true years later. After gaining considerable influence over the wife of Tsar Nicholas II, circles close to the Tsar wanted to get rid of him during World War I. On December 16th 1916, they poisoned him first, then stabbed and shot him, before throwing the still-living Rasputin into the freezing Neva river, where he died by drowning under the ice-cover.

Ironically, that exactly had been his nightmare.

Trivia

 * In reality, Rasputin's death had been much more profane. After the conspirators had trapped him, they'd tortured him for hours to get information, before executing him with three shots and dumping the body into the Neva.
