The Sinister Six
Kellux Antigua is the Steward of Nighthold, generally accepted to be Nightstalker’s second-in-command. She is a female dark elf vampire Wizard, with dark blue skin instead of the more traditional ebony skin.
She is known to have several vampire servants and underlings, one of which was previously purported to be Taxx Murgen until Murgen’s direct bonding to Nightstalker was revealed.
