[quote]I think that the lore revealed in the last step of “The Lie” quest was quite interesting, but I’m still left scratching my head over something. What exactly was Rasputin’s investment in Felwinter? What was it Felwinter did that made Rasputin single him out and hunt him down and destroy him? What is their connection?[/quote] Felwinter (pre collapse) was a Sidhartha Golem. These are Exo’s programmed to research information (mainly literature, art, music, media, etc) and give it to Rasputin in order for him to go on to possess an exo with all this info and become more human. So he could walk amongst humanity. Rasputin regarded him as a “son” and didn’t want what he had, all that info to fall out of his control. So after many failed attempts at killing him with warsats and frames. He led not just Felwinter, but all the Iron Lords to SIVA and killed them (except for Saladin Forge and Lady Efrideet who’s already left the order years prior).
