Revolution
The times in which the Orcs, Dark Elves and Goblins rioted for the permanent illegalization of owning slaves: these races have been enslaved by Overlords ever since the tyrants rose to power, and it started with a group of Orcs founding the abolitionism movement.
Led by Ravgaal the Chainbreaker, an army of Orcs, Dark Elves and Goblins march on the stronghold of Alfric the Cruel, in an attempt to free their people forever.
