The old road east from Ervessos to Grancazarel skirts the northern edge of the Madding Plains, but no major roads pass through the heart of it. The Madding Plains are the only place where the frensy flowers grow and when those flowers bloom, madness reigns.
The flowers with colors reminiscent of dancing flames have a pollen that can intoxicate most humanoids. In low doses it is consumed recreationally in honey or alcoholic beverages, particularly popular in Mayura. When it is breathed in a concentrated form or for an extended period, individuals can enter an enter a state of ecstatic mania. Those that seek out this experience repeatedly are called Madders.
Madders eke out a meager living on the plains, foraging edible plants and stealing the eggs of the flightless owu (and sometimes getting killed or injured) for sustenance, but when the blooming of flowers peak, they in the heart of the area for a raucous festival. On some years they stay there, but on others the revelers breakup into smaller bands that rove wider region becoming a nuisance and sometimes a danger.
Halflings are the other group which live in the plains. Of all the mortal peoples, they alone seem immune to the frensy flowers powerful effects. They do much of the collecting of the honey made from the flowers and brew the mead made from it. The Madders can sometimes be an impediment to this, but the halflings don't let this deter them from their chosen livelihood.
More than merely an economic endeavor, the halflings view the harvesting and brewing as a sacred duty to a god that did not abandon the Earth with the others but instead sleeps (perhaps sleeping off a hangover) beneath the plain. Bok, as they name him, is the god of intoxication and the brewer's art. They depict him as halfling-like in stature, with an un-halfing-like girth (Parsulan halflings are un-Hobbitishly thin) and shaggy-fetlocked, cloven hooves.
