The stories revolve around Captain Jack Dancer and the crew of his ship the Red Wench. It mixes pirates with anomalous phenomena, including magic, zombies, the hollow earth and werewolves.
Jack Dancer: Captain of the Red Wench, late of The Royal Navy. Having encouraged his crew to rebel against a tyrannical Captain, they elected to follow him into a life of piracy on the high seas, forever on the run from British justice.
Ginger Tom: Jim's father. A grizzled old sea-dog.
Swinging Billy: A straight-talking, somewhat overweight Scot.
Jim Salt: Tom's son. A cockney teenager who was killed by Isabella during the events of "The Hollow Earth", leaving Tom heartbroken. The formless entity known as Hnau entered into Jim's corpse, thereby gaining the means to explore the world he had so long ruled over.
Julius: A young black sailor, illegitimate son of a famous London composer.
Erebus: An immortal, double-headed dog's head on a robotic chassis, formerly guardian between the realms of the living and the dead, a role in which he seemed to be largely analogous to Cerberus of Greek mythology. The heads of Erebus have been a vital part of the crew, possessed of a wealth of knowledge of the mythic and arcane adversaries which Jack's crew frequently find themselves facing.
Alexander Dancer: a late addition to the crew, half-brother of Jack.
