Warthak was a powerful warlord who controlled and oppressed many regions with his army of chaos dwarves. He seemed unstoppable until General Atum made his appearance, liberated the regions under his oppression and sent him away. Now Warthak is back to re-write the end of that story.
After Lord Nebotus reinstated Warthak as leader over the mountain dwarves during his brief rise to power, Warmaster Gortak tolerated and supported his leadership, as this time he showed some respect for the people he was presiding over. He eventually stepped down in favor of King Atum.
