As for the Orcs, well after the Great War of the Old World, the Orc tribes, under the leadership of Slaarg the Mighty, underwent a metamorphosis. They still smell and they still expel gases that can offend at 40 yards, but the ‘New Age Orc’ is a far cry from the drooling psychopath of old. They even mimic their old enemies and some tribes now wear clothes!
There are only two things Orcs hate more than Dwarves: washing and Elves!
