Stop the Insanity!

[Slogan]

I found R'lyh to be one of the hardest nations to play. As was stated they consume a lot of gold and by the time they get strong enough to move onto land their armies are dwarfed by the other nations. Thanks for the tips on Void Summoning that was driving me insane! What about the other sites to be entered, I've had much trouble entering the sites that improve combat, do they need a particular unit to enter?
