Rick Turpentine is a former highwayman who appears as a random event. When talked to, he gives players some loot or a kebab or spinach roll, as atonement for his past crimes.
Prior to the random event update, if the player ignored him, he would attack while taking the player's coins.
Rick Turpentine is likely based on Richard "Dick" Turpin, an 18th century English highwayman who was executed and romanticized as dashing and heroic after his death, becoming the subject of numerous ballads and plays.
