The Sinister Six is a group consisting of six deadly mercenaries who are close associates of Galeras Matheson. Although they've mainly worked for the Matheson Crime Family in the past, after Galeras's capture in Jardine in 1017 AE they've branched out and offer their services to the highest bidder in the criminal underworld and are currently doing odd jobs to various criminal organizations such as the Dwarven Triad.
