These victims of bad birth are utilized as best as they can be, as laborers in the mines. Anyone who spends too much time in the mines tends to come down with 'mine sickness,' hair loss, vomiting, and sores. The Fomoria are the only people who seem to be immune to this malady, perhaps because it produced them. This lowest order of Giant-kin believe that a demoness lives in the mine and that the materials they remove are her, er, droppings? (that being why the stuff is so toxic), and the Fomoria are her people.
It can be expected that a Fomorian fortunate enough to leave Jote will be either a Cleric, a Fighter, a Thief, or a Psionic. Multi-class Fomoria have also been spotted (any two).
All Giant-Kin speak the same language, called Jote, and a Fomorian can choose from Ancient or any of the languages spoken in the Shattered Lands, intelligence permitting, of course. Other languages are possible, but must be explained to the DM's satisfaction. Jote uses the Ancient alphabet.
A Fomorian has exceptional resistance to toxins, just as a Verbeeg does. He gets a bonus of +1 for every 3? points of constitution (see Table 9 in the PH).
The Fomoria have infravision out to 60 feet in the dark.
As Fomoria are usually very out of proportion, they get stuck with a movement rate of 10.
Despite their hideous appearance and low intelligence, Fomoria have an excellent chance to have wild psionic talents (add 5 to base then multiply by 3 before roll).
Because of their size and build Fomoria get to add 1 to their strength. They are very hideous or even nauseating people and should subtract 1 from their charisma and 5 from their comeliness. They also have a high tendency to be as stupid as the Firbolg are smart, reflected in a minus 1 on intelligence (some people think that they simply aren't given a decent education, so they don't know how to think).
