As I continued to watch the video, the implications of the reaper war became clear. Wraiths and Phantoms would be waiting for invasions, constantly on edge.
From what I gathered, the invasions would be similar to a covert operation in modern day combat. You would have an unknown force that would wreak havoc in your domain.
Phantoms would be like the mayors for each zone. The Wraiths would be both their citizens and soldiers. Specters, on the other hand, are like adventurer parties in novels. They went to slay the dragons.
The clear division of roles allowed for responsibilities to be black and white. Everyone would know what to do and why. In a perfect world, the roles should have been reversed. You would take most of your military might to attack and reserve a few to defend.
If Lilly and her white-uniformed posse were just Phantoms, how powerful must Specters be?
