If one were to travel northeast from Thursday City into the surrounding Valley of Keene, across the river, deep into the heart of the Back Woods one would eventually arrive at the Dark Prefecture. A magical place filled with wonder and made all the more intriguing by the decades of accumulated folk tales surrounding the area. One would most certainly get there eventually; if one were so inclined. Once there one may or may not encounter Le Gooch the prince of the Dark Prefecture.
Le Gooch is a divine creature, a deviant perversion of divinity perhaps, but divine nonetheless. We do not know whether he protects or terrorizes his territory, possibly both, but regardless he is there. There is no documented evidence of his existence in this realm, but trust me he is there. It is rumored that he has been responsible for devouring men, sacrificing women, and (inexplicably) de-limbing philosophers and heroes. Believe what you will.
