In 1988, Schuiten and Peeters took the opportunity of the second French edition to revise their story, adding content tying into subsequent Les Cités Obscures publications, and clarifying ambiguities of the original.
In 2007, a new French printing was further appended with Les Mysterères de Pȃhry, a collection of four previously published story fragments relating to the city of Pâhry.
Attempting to break into another hotel room, Franz discovers that all buildings and streets in Samaris are actually mechanized façades automated on rails, and that all the people he met were lifeless dummies.
He falls into an engine room and finds a book that seemingly describes the nature of Samaris, comparing the city to a carnivorous plant that sustains itself by capturing visitors and creating "effig[ies]" in their image.
As the council demands answers about his mission from an age long past, Franz declares Xhystos a fake and sets out to return to Samaris.
