In short, pretty much a copy of Warcraft retcon. For my taste, the campaign tried too hard to make orcs looks abused. There's nothing genuinely likeable about them, their culture is barely more developed than those of Tolkien. I recommend reading Poul Anderson's "Broken Sword" for an interesting example of a villain half-troll with developed personality. It's a great story from start to finish, and would be wonderful for inspiration. It describes a war between trolls and elves in a way that feels epic without being overblown. It's a forgotten classic and one of best fantasy books ever written. Tolkien and Anderson drew from the same sources, but used them in different way.Crim, The Red Thunder wrote:The lore in orc breeding grounds talks about infusing corrupting blight into the mothers blood. Personally, I believe the current state of the orcs is being affected like this. The blighted blood in the offspring generates excessive aggression, retards thinking, etc. et

Orcs in Tolkien's works came... from elves. They were elves captured by Morgoth (Sauron's boss) in the dawn of time, and twisted with torture and dark magicks. Which reminds me a bit of George's Orwell's "1984".
