Tusk is a name given by Orks to a world at the heart of Undred-Undred Teef.
Here greenskin ranks are thickest and the battle between them is fiercer than on any other. Powerful Warbosses and Freebooter Kaptins gather here to test their mettle in the greatest fight in the Expanse. With every passing cycle of conflict, the number of bosses grows fewer, and those who remain are more powerful and grow to ever greater size. Above Tusk’s surface a huge Space Hulk orbits, and millions of Orks and Gretchin work under the direction of Mekboys, fitting engines and weapons looted from the ships of other races or built in workshops scattered across Undred-Undred Teef. The Orks of Tusk stand on the edge of a great Waaagh! that, if not stopped, will shake the Expanse and the reaches beyond. Greenskins from all over Undred-Undred Teef gather on Tusk in great numbers, feeling the gathering Waaagh!, and all that it waits for is an undisputed boss to emerge from the chaos of Ork fightings.
