Writer Ian Edginton has begun linking his pseudo-historical strips together, both covertly and overtly. Images of both Jack Dancer from "The Red Seas" and Hastur from "Leviathan" later appeared in "Stickleback"; the pub "The Jolly Cripple", a haunt of the "Red Seas" pirates, reappears as the haunt of the character Detective Valentine and contains a portrait of the original proprietress from "Red Seas"; and "Leviathan" villain William Ashbless briefly appears in "Stickleback" as a member of the sinister City Fathers group.
