Father Huxley was the Mechanist who headed the Mechanist temple in Lord Gervaisius's estate. The temple had previously been a Hammerite temple kept by Father Norrell, whom Huxley believed to be a senile old fool, but Lord Gervaisius, influenced by numerous gifts from the Mechanists, as well as a concerted effort by both Huxley and Steward Duma, eventually decided to switch faiths.
Huxley was pleased with his position in the Gervaisius Estate, and felt the upcoming exhibition would be the perfect opportunity to show the nobility the wonders of the Mechanist faith. (T2: "Masks")
