Christia Sylf was the pseudonym of Christiane Léonie Adélaïde Richard, born 28 September 1924 in Paris, died on 28 November 1980 in Entrevaux (Alpes-de-Haute-Provence).

The novel tells of the conflict between the sorcerous Queen-Mother, Abim, and her daughters Opak, who rules Kobor Tigan’t, the five-levelled City of the Giants, and her sister, Ta.

The world of Kobor Tigan’t is inhabited by a race of reptilian bisexual humanoids, the T’los, who are used as sex slaves by the Giants.

Unfortunately, these works were never published because Sylf died in the early 1980s, soon after the publication of La Reine au Coeur Puissant [The Strong-Hearted Queen] (1979).
