I also agree that this would be an excellent way to create Orcs for a longer game. I especially enjoyed that they weren't limited to the standard fantasy trope depiction, and that although they are warlike creatures, it's because they were specifically created as living engines of war by unscrupulous sorcerers, and the actual culture of the Orcs and their relationship with the Lannians is just important as the weird gribbly bits and various distortions of their harrowed flesh.
