Carlo "Cleaver" Varese

Carlo Varese also known as "Cleaver" is located in Novigrad and is one of the four main crime bosses of the city alongside Francis Bedlam, Whoreson junior and Sigi Reuven.

He is by race a Dwarf whose gang is primarily made up of other dwarves. This is seen in the quests "Of Swords and Dumplings" where the people sent to ambush Geralt were dwarves. Also seen in the quest "Get Junior" where, if you side with Varese to get Whoreson, Geralt and Cleaver's men (made up entirely of dwarves) raid Whoreson's casino, fight club and house.
