The Port of Bellow is the largest entrance to the underground, in the toothless skull of the god that created anger. It is not the greatest city of the mushrooms, but it is the most prominent.

The melodic concert of mushroom gill-speech rings throughout the cavern, welcoming meatfolk (or, when they wish to insult, "fertilizer) to their domain. Unlike other mortal races, the mushrooms all swear fealty to one King, who has never been seen, but whose tendrils spread throughout all known lands.
