World of Warcraft: Tides of Darkness

The orc War Chief Blackhand is dead, but the Orc Horde has not crumbled as expected. Instead, a new War Chief, Orgrim Doomhammer, has risen to power, and his forces are stronger than ever. The free peoples of Azeroth are scattered and unable to stop the orcs' advance. The human lord, Sir Lothar, knows his people stand little chance against the dark tide of the Orc Horde, so he hatches a desperate and unlikely plan: to enlist the aid of humanity's rivals, the mysterious Elves and the wily Dwarves.
