Okay. During the events of Green Run, Die Rise, and Buried the characters (Marlton, Misty, Russman, and Stuhlinger) built 3 pylons that gave power to both Maxis and Richtofen. Depending on the voices Stuhlinger listened to, Maxis or Richtofen would gain power over the zombies. At the end, Maxis ended up getting power due to the first choice in the op.
After the crew died, Richtofen got sent back into Aether (state between life and death) and is once again trying to gain power.
Since you decided to destroy the 3 pylons, nobody has power anymore and now Maxis and Richtofen both don't have power over the zombies. In order to regain control, Richtofen needs to instruct another group of survivors to reconstruct them, thus restarting the power struggle 'cycle' once again.
Now that the only power you have left is influence, you must roll back time and start again.
