Red Bull

The Red Bull was a demon servant of the chaos god Ahriman. It was banished to the Great Plains by the Gods of Law at the end of the Great War of the Gods. It was later sought out and subdued by a sorcerer, who chained it to a ship and sailed it to the continent. The sorcerer took his father's throne and used the Red Bull as a weapon in the War of the Three Kings. Eventually, it broke free of its chains and slew its master, wreaking havoc across the land, until the hero Giliad brought down the beast with a hammer that was forged for him by the Dwarves of Vorn.
The Red Bull was called from across the horizon by its master, Ahriman, to aid in the Great War of the Gods. It killed many elves, impaling them with its flaming horns. When the Chaos Gods were defeated, the Gods of Law debated as to what should be done with the bull. A shepherd overheard, and offered to tame it. The bull was spared, left free to roam and graze on the Great Plains. But the gods were tricked. The shepherd was a servant of Ahriman, and wore a shroud to conceal his identity. He was later known as Balok the False.
