How does the Temple of Secrets work <spoilers>
I completed a quest that game me the possibility to build the Temple of Secrets. The description says that its quiet, but if the city is attacked it will have forces that will help. This means extra city defenders I suppose. It also says that they will act as mercenaries for those who can afford it or something like that. I cannot recruit any new units in this city. Will I get a popup with offers or something???
