Taurus is a Champion under the command of General Luxurius who is encountered near Decimus' House in the Crow's Nest district of Aleroth during the events of Divinity II: Flames of Vengeance. He resides at Taurus' House, across the street from the Cosy Dwelling on Lanilor Lane.
He is found chasing Tom, who has began stirring up trouble for Luxurius since his girlfriend Anne was abducted to serve as a sex slave. Tom frantically asks for your help before Taurus catches up, saying that he is about to get killed. No matter how you respond to the situation, violence is inevitable (either you defend Tom and Taurus attacks you, or you tell Taurus that you won't interfere and he replies that there can be no witnesses and attacks you).
After the encounter Tom asks for your help, beginning the quest Beauty And The Beast.
You can mindread Taurus for 22500 exp to reveal: "This joker has another thing coming if he thinks he's a match for me and my enchanted bracelet!" This allows you to loot Taurus' Bracelet when he is killed.
The beggar Darvesh, who can be found sitting in the Mardaneus Plaza district, knows a secret. He'll tell you where Taurus' Shield is hidden (allowing you to steal it) if you give him three gold coins. He says that you shouldn't feel bad about taking it because Taurus is "one of the most feared and hated men in town!"
