Volatix Cabal
The Volatix Cabal were a secret Dalek society who operated during the Last Great Time War. They were created by the Daleks for possessing a talent that no Dalek could possess: creativity. (COMIC: The Organ Grinder) They were distinct from the Dalek Empire, and their motto was "Exterminhate". The Cabal were active at the start of the War, but they disappeared before it ended. (COMIC: Downtime)
The Volatix Cabal had a base on Golgalith. The War Doctor and the Master killed one of its members near where the TARDIS landed on the planet. Volatrix tendrils captured Alice Obiefune and scanned her mind for memories of the future. The Squire saved Alice from them, killing all members of the Cabal inside the base.
