Lord of the Clans

Enslaved as a gladiator from infancy and raised without knowing his own orcish name, Thrall escapes captivity to search out the remnants of his people, broken and demoralized after their defeat in the Second War, and begins gathering the scattered clans back into a Horde worth the name. Christie Golden's novel is the origin story behind one of Warcraft's most consequential leaders, later folded into the games as Thrall's canonical backstory.
