So i'm trying to get to Triumph Square for our Pantheon, slowly building up the Power requirement of 4k at the moment. Is there other buildings that are required to be built first? Is there a Flow Chart or something that will explain all this? I find the quick tips on the Stronghold tab leave a lot to be desired and I noticed that even though I have more than 1k power, I still can't build the 1k required buildings? Do I need that 1.5 million building first?

If it helps, I currently have:

7 Clans

7 people can be in each clan

Whatever 2 million cost building that gave initial 1000 power

1 upgrade for another 1k power (Maybe 2 by the time I get home)

Thank you,
