Reef was a fair-haired Nilfgaardian and one of the members of the Rats. He spoke with a distinct accent and had a naked woman tattooed on his forearm. He often took fisstech. He and the entire gang, with the exception of Ciri, were killed at the hands of Leo Bonhart in Jealousy. Before becoming a Rat he had licked his wounds alongside Kayleigh, another Rat to be.
“
Reef was a soldier from a punitive expedition, which Emperor Emhyr Var Emreis had sent to crush the rebellion in Ebbing. He was one of the soldiers who had captured and plundered the stronghold after a two-day siege. Having captured it, Reef's comrades abandoned him, although Reef was still alive. Caring for the wounded was not a custom among the killers of the Nilfgaardian special squads.
