Grog is the High Chieftain of the Mauthian City known as Sauria. Grog is one of the rare few to have his own personal bond with a TREX, which he has named Tooth. Grog is the best warrior of the Mauthian Chieftains, using a trident and mace in combat. He bears incredible strength, and is skilled in guerrilla warfare tactics. He is renowned by many to be highly intelligent and a great negotiator. When he rose to status of Chieftain in Sauria, he secured a deal with the Argentan Empire in exchange for giving Argentan Elite warriors access to their own dinosaur livestock to be used in reconnaissance missions against enemy Pillager Armies. In return the Argenta gave his tribe many Argentan products such as food and gear. This led to the Mauthians destroying enemy tribal groups, and gaining supremacy over the other tribes.
