Myth: Orcneas, Master of Masters Expansion Boss

From the publisher's website:

Muckers who continually survive combat grow in size and strength until they become a warchief. Orcneas, called “Master of Masters” by the Grubbers and Muckers who follow him, is one such leader. Riddled with scars and wielding two axes the size of men, Orcneas charges into combat felling any who stand against him. His roars of rage and command affect heroes and minions alike. Those who dare to harm Orcneas find he has many surprises in store for them.
