The ground trembles as an army of 230,000 advances. A continous noise of thousands of feet trampling the ground beneath it, like a giant snake sliding smoothly across the lands.

Up close it's the sound of chainmail and armor clashing together which overpowers all other sounds. The creaking of wood of the supply carts and siege engines can be heard only faintly and the growlsg and grunts of the war animals are all but drowned out completely.
Nobody speaks a word to each other, partially due to the overwhelming noise around them, but mostly due to their focus. The army is a mismatch of separate groups, but despite this they do share the same goal: Kill the enemy and make it back home.
