Humans are very emotional beings, and feel things much more strongly than most other creatures. Sometimes, they feel things a little too strongly.
I have never been happy with the way that magical constructs were presented in games. Admittedly, a large statue stomping the surrounding countryside is an impressive image. But the logic (or lack thereof) involved has always bothered me.
Termites, in certain places, make homes that can be eight meters high and only a half meter wide. They are built facing North to South to take advantages of the suns travel, maximum heat in the morning and evening and little in the afternoon. Imagine grassy plains with vertical structions facing a certain direction all over the place. Ambush? Maze? New creature? Larger structures?
