My question, who was the eighth soldier, the reader? Was it merely because we read the issue allowed the story to happen?
I took the 8th soldier as being I, Spyder, who (since Mister Miracle was killed) was actually the 7th Soldier, preserving the group's number.
All the references to Cryus Gold? Were they to represent the resurrection nature of comic book stories?
It was a number of different things - Cyrus Gold was turned into a grundy by the same method as the grundys in Klarion's book. Turning Zor into Cyrus Gold was commentary on rewriting comic history/retconning (I think Doc pointed that out pages back but I don't remember).
