Warcraft: Lord of the Clans is a novel by Christie Golden based in Blizzard Entertainment's Warcraft Universe. It was published by Pocket Books. The story of the novel was originally going to be used in the adventure game Warcraft Adventures: Lord of the Clans until it was canceled. It is the second book released in the Warcraft Universe after Warcraft: Day of the Dragon. It is part of the Warcraft Expanded Universe.The book tells the tale of Thrall, a young orc orphaned by assassins who kill both his parents. After being found by a human named Blackmoore, Thrall is taken to his castle, where he is raised to fight in gladitorial games to earn the alcoholic Blackmoore money. After escaping the castle with the help of a human girl, Taretha, Thrall travels to reunite the orcs.
This book contains the following tropes:
Adaptation Distillation: The original source for the plot was a Full Throttle-like game starring Thrall, which was then cancelled due to it not meeting Blizzard's quality standards. Someone managed to get a hold of it here. The original game had a lot more continuity nods to Warcraft II, and some of the major plot points were greatly revised in the book (though it is hard to tell how much due to missing cinematics). There is no sign of sympathetic human characters such as Sergeant or Taretha in the game either.
Always Chaotic Evil: Subversion is the whole point. This is the beginning of the the end for Orcs' long-standing reputation as the embodiments of nastiness.
Aristocrats Are Evil: Blackmoore comes from a shamed noble house. He is willing to reclaim the family's position by any means necessary, including raising Thrall to use as a puppet general, thereby gaining command an army of orcs to use against Lordaeron.
Captain Ersatz: A lot of Thrall's backstory owes itself to Ben Hur and Spartacus. Thrall, of course, ends up better than Spartacus.
The Clan: The Frostwolves are all a bunch of uniform good guys. They're JERKS to Thrall in the beginning, but they're good guys.
Hoist by His Own Petard: Blackmoore raised Thrall to be the perfect warrior who could lead the orc armies against the rest of the human Alliance. Thrall did eventually become the Warchief of the Horde... and then led his army against Blackmoore.
The Horde: Thrall makes The Horde 3.0. It's not yet an Alliance, consisting of just orcs.
Humans Are the Real Monsters: Subverted. The main villains of the story are all human, and by the end of it, you're cheering Thrall on as he and the Horde storm Durnholde. At the same time, however, Thrall is well aware of humanity's capacity for good as demonstrated by Taretha and Sergeant, and when he sees the collective spirit of the human race during his shaman training, he finds that it's closer to his human friends than Blackmoore.
Ineffectual Sympathetic Villain: Langston to a certain extent. Blackmoore is actually just a gigantic bully but does too much evil to be considered sympathetic.
Lethal Chef: Blackmoore hired an old comrade from the war as a chef, whose fish has made Taretha ill more han once.
Magic Knight: Thrall is proficient in both melee combat and spellcasting (as a Shaman).
Meaningful Name: Thrall keeps the name, which means "slave", so that neither he nor Blackmoore will forget what the latter has done when the former comes back with a vengeance.
Messianic Archetype: Thrall is basically a cross between Moses and Spartacus, plus some green paint.
My Master, Right or Wrong: During the siege, Sergeant sees that Blackmoore's gone mad and that Langston is completely useless, but takes up the responsibility of defending the keep because they all think that Thrall won't stop until Blackmoore's dead.
No Dead Body Poops: Averted. A reference to the "stench of urine and feces" is made a couple of times when describing battles.
Secret Test of Character: Drek'thar demands respect from Thrall after meeting him, but is impressed when he refuses to accept being treated like a slave, noting that he proved that he was humble, but not an Extreme Doormat.
