Ork gunmen and archers picked off who they could on the wall, but volleys of projectiles flew in both directions. A battering ram was rolled up to the front gate, but from father off, a trebuchet began deadly work on another section of wall. It only a matter of time before orks broke in, their greater size allowing them to overrun any physical hindrances, slaughtering all in their path. Sometimes, the old ways were the best. You didn't need magic or tech to take out a stone wall. Giant rocks worked just as well. Damien of course, knew this city and its weak points. He knew the layout, the secret back doors, the sources for water and fuel, and where the citizens would be gathered, hiding from the battle. They had no idea how little chance they had. A city ruled by chaos needed the order of Asmodeus. This was all inevitable. 

The human necromancer heard the sounds of falling rocks as part of the wall gave way to a flying boulder. A cheer errupted from the ork warriors. ...not long now.
