We can say relatively little for certain about the life of Robert W. Chambers, but it is clear from his work that knew France and its history. For this reason it is tempting to believe that the name Hildred Castaigne, unreliable narrator and protagonist of the classic Yellow King story “The Repairer of Reputations,” took its inspiration from the early 19th century murderer Edme Castaing.

Castaing, a young and impecunious doctor, befriended a pair of wealthy patients, the brothers Auguste and Hippolyte Ballet. In 1822, the consumptive Hippolyte died while in Castaing’s care. His fortune went to Auguste, who made Castaing his heir. Half a year later, after drinking wine and then milk given to him by Castaing, Auguste also died after a prolonged fit of vomiting.

Both victims had been in their early twenties. This fact, added to Castaing’s financial activities, triggered official suspicion. Investigation focused on his purchase of a then-new medicine, morphine, before the deaths. Castaing was arrested and tried for murder. The jury found him innocent of Hippolyte’s death but guilty of destroying his will, and of murdering Auguste. He went to the guillotine on December 6, 1823.

In the entangled realities of The Yellow King Roleplaying Game, the mere difference of a few letters in a surname doesn’t stop us from identifying Castaing as an unlucky link in the dynastic chain running from the Pallid King to Hildred Castaigne. He had all the sinister predilections of his family without a Mr. Wilde to fully usher him to his destiny.

Ghosts feature heavily in Chambers’ other, lesser horror tales. In keeping with those, the characters from your Paris sequence could meet up with this earlier, slightly misspelled member of the bloodline in phantom form. Perhaps they encounter Castaing’s shade at the Place de Greve, the site of his guillotining. Or in Saint-Cloud, the bucolic Parisian suburb where he poisoned Auguste, during their stay at the Tête Noire Hotel.

Like other Chambers ghosts, Edme might not look or sound dead at all. He could seal his friendship with the occult-busting art students with much-needed medical treatment. His unearthly healing powers might allow the discarding of Injury cards that aren’t normally gotten rid of with a First Aid success. Over time Edme might abuse his friendly GMC status to mislead the group into spreading the influence of the Yellow King, increasing his own powers. Only by researching the seventy-year-old story of Edme Castaing can the group discover that their apparent benefactor is neither alive nor on their side.

Naturally, if he suspects they’re onto him, he’ll reach for the syringe full of phantasmal morphine he keeps in that little black bag of his.


The Yellow King Roleplaying Game takes you on a brain-bending spiral through multiple selves and timelines, pitting characters against the reality-altering horror of The King in Yellow. When read, this suppressed play invites madness, and remolds our world into a colony of the alien planet Carcosa.
