After discussing with John and Peniel, Jack decided to leave the Legion Hall and Killer Abode for later. Those two gave new special units but they didn't gain the units right away. It would be some time before the soldiers applied for class change and started becoming one.
They agreed the other three gave better benefits in the coming war as well as for future needs.
Jack proceeded to build the Revival Pool and Soul-securing Shrine. Jack chose Theneward and Thehemburg as the settlements to place these wonder buildings. Theneward and Thehemburg were the two most populous settlements after Thereath. The wonder building had the hidden effect of increasing population growth. It was better to have every metropolis have at least one wonder building if he could afford it. He spent 12 ruling powers to complete the construction.
As Peniel informed, the Soul-securing Shrine and Revival Pool had similar functions.
