Spoilers: Character background, including Greasus’s rise to leadership; no campaign ending.

The son who took the tribe
Greasus was a son of Gofg, the Tyrant of the Goldtooth tribe. He grew into a powerful Ogre, then killed and ate his father. That act made his claim to leadership brutally clear and established the ruthless reputation behind his rise.
Other Tyrants joined him as word spread. The Goldtooth leader became an Overtyrant, extending his authority beyond his own tribe. His position grew through the willingness of other Ogres to follow someone who had already demonstrated his strength.
A richer Overtyrant still wants more
Wealth became another mark of Greasus’s power. His treasure continued to grow even as he became older and larger, but success failed to satisfy him. His appetite for possession and conquest remained central to the character.
Strength and wealth therefore belong to the same portrait. Greasus has enough of both to command others, yet still seeks to add to his holdings. His imposing appearance and royal trappings express the status he has accumulated.
Greasus in Total War
Total War: Warhammer III gives Greasus command of Goldtooth. Tyrant’s Demands turns the Overtyrant’s wealth into campaign actions. Immortal Empires then leaves the course of his wars and alliances to the player.
Skrag and Golgfag show other Ogre ambitions: devotion to the Great Maw and a career of mercenary employment. Their campaigns share an army tradition with Greasus while pursuing different goals.
The claim, the road, and the last Overtyrant
Andy Hall's introduction calls Greasus the greatest and the fattest ogre alive, or so Greasus claims. The roster strings the titles together: Tradelord, Tribestealer, Drakecrush, Gatecrasher, Hoardmaster, Goldtooth, the Shockingly Obese. He is one of many whelps of Gofg, tyrant of the Goldtooth tribe. Unlike his brothers, he killed and ate his own father. The same piece says the father was stewed. It leaves the siblings' later fate unstated.
More than a century had passed since the last Overtyrant. No ogre since Donner Gutbag had pulled the tribes into one kingdom. Donner is not a playable lord. Goldtooth territory crossed the Ivory Road, the trade route through the Mountains of Mourn between Grand Cathay and the Old World. Earlier tyrants, his father among them, plundered the caravans. Greasus turned violence and treasure into bribes, blackmail, and better arms. He grew older, larger, louder, and richer, and the hunger to conquer what he sees remained. He is too rich to walk, so gnoblars push a cart of gold.
That is the portrait. In the campaign, Goldtooth spends Treasury on Tyrant's Demands. The bargains after the start are the player's. Skrag serves the Great Maw. Golgfag sells the axe. Neither of them is Overtyrant.
