|The Revengers' Club|
|Notable Members||Billy-Ray Sanguine, Dreylan Scarab, Dusk|
The Revengers' Club was a group of past villians in the series. They all have different objectives, but their main one is to destroy the Irish Sanctuary.
The club was formed by Dreylan Scarab after he was released from his Arizona prison 'a few days early'. The group's apparent aim was to get revenge on Skulduggery Pleasant. However, as events unfurled, many members of the club presented other motives: Dusk claimed to have came out of curiosity, Vaurien Scapegrace to realize his dream of becoming a "Killer Supreme", and Remus Crux, the psychopathic worshipper of the Faceless Ones, as well as Billy-Ray Sanguine, revealed to be Scarab's son, wished to exact revenge against Valkyrie Cain. Dreylan Scarab wanted revenge for being framed for the murder of an important figure (Esryn Vanguard) during the war with Mevolent.
The club planned to get their hands on the Desolation Engine to kill a thousands of people live at the All-Ireland Championship. In doing this, the Sanctuary would never be able to recover, and the other Sanctuaries around the world would "tear the country apart and fight over the remains". To do this, they captured Kenspeckle Grouse and used a Remnant to possess and control him, forcing him to repair the Desolation Engine. After tricking Thurid Guild into arming the Engine, their plans were foiled when Fletcher Renn teleported Guild and the Engine into the sea. Most of the members were arrested, but Dusk, Sanguine and Scapegrace escaped. Shortly before the All-Ireland championship, Remus Crux was murdered by China Sorrows.
