..."Rasputin was awoken Post-collapse"... Not true... Rasputin ordered Operation SkyShock immediately after the detection of the darkness, and the subsequent prediction that the traveler was going to flee. Essentially, Rasputin detects the traveler is attempting to flee from the darkness and leave us as fodder. So he initiates Sky Shock and blows the heck out of the traveler, crippling him, and making him stay to help us.
