The train never goes to Nequinium any more. The folk of the road call it “the city of lost monsters” where all the creatures that crawl out of the abyss make their way, living amongst themselves in a mockery of the silver city. There are rumors also of ancient cities within the mountain and of strange debaucheries in the city.
Peco and Jon only say that the city is empty of civilization and filled with all the monsters of the abyss; the ocean has receded from it , the bogs are encroaching upon it, and the smell from the ocean is unbearable. There’s no reason to go there.
Nequinium is populated by the monsters of the abyss, and by a race of winged people.
