Which faction’s city do you like the most?

Back then, Necropolis was the faction that impressed me the most; I just couldn't get enough of it. :)

But I was disappointed by its dark energy. Now, you can't really resurrect a decent army. So, you have to keep a couple of completely useless necromancers, and thanks to the pillars of knowledge and the trees that give experience, you can at least level them up a bit and increase the amount of dark energy.
