Firbolg

Firbolgs resembled humans, and the males would sport great, thick beards. Their thick, tough skin was fleshy pink, and their hair, though it came in many colours, was usually either red or blond and worn long. A firbolg's voice was deep and smooth, and they tended to roll their consonants when speaking.

Firbolg pregnancies are typically about two years long. This is much longer than other giant-kin, who have pregnancies roughly equivalent to humans. Firbolgs reach adulthood at about 30 years, and can live as old as 500 years. Some scholars postulated that this long life is because Firbolgs have fey blood, but most giant races have long lifespans.

Firbolg's tend to grow at a similar rate to Humans and reach maturity at the same age.

Firbolgs have a family-centred, clan-based society. They live in settlements in remote hilly or forested areas. Their settlements are strongholds, including wooden structures, built from the trees around them, with defensive towers with catwalks between them. Rarely, they inhabit cavern complexes dug into the hillsides. They use their magic to ensure that their homes remain a secret to outsiders. These clan settlements are small, with between about four and sixteen members, often with a shaman or druid, and lived separate from each other. A few firbolg clans are nomadic. A typical firbolg home is a huge one-story log building with strong walls. A large fireplace with multiple openings warms a central common room.

Firbolgs have their own tongue, but also speak Common, Giant, and Elven. Sometimes, Firbolgs who interact with outsiders take elven names. The traveller Volothamp Geddarm reported that Firbolgs have no names for themselves or their homes, but there are many named Firbolgs and tribes in the Kindernia Enclave.

As caretakers of the woods, they carefully and resourcefully live off the land, making sure to ensure balance. During summer, they store excess nuts, fruits, and berries, so that they can provide food to the forest animals during winter. Although they do farm, it is only to supplement their diets; they prefer a more hunter-gatherer lifestyle, rather than the brigand/raider lifestyle of many other giants. Their hunting grounds are usually spread out in a 20‑mile (32‑kilometer) radius from their clan homes. They eat small portions of meat with most meals, and reserve large roasts of meat for special celebrations. Most Firbolg tribes prefer isolation from other races, avoiding their politics and struggles. If intruders enter their territory, they will usually try an indirect approach at causing the "invaders" to leave—driving game away to discourage hunters or redirecting streams or forest trails to confuse parties. If these methods fail, the Firbolgs will at last confront the outsiders. If the outsiders seem peaceful, Firbolgs will peacefully ask them to leave; if the outsiders seem evil or seem to have no concern for the forest lands, Firbolgs might mount a devastating attack. On occasion, they might trade with peaceful folk living nearby in exchange for providing services utilizing their great strength.   Firbolg communities are known to rally around individuals who contract lycanthropy, rather than shun them, using all resources at their disposal to help the afflicted find a cure.

Firbolgs are a reclusive race of giant-kin who preferred to avoid contact with other sentient races. They are both the most intelligent and the most powerful of the giant-kin.

Firbolg adventurers are rare and most often are individuals separated from their tribes—orphans, exiles, lone survivors, or the like. A few adventured to gain knowledge. Firbolgs seem to have a natural tendency toward druidic magics, and many of their chieftains are thus druids. Others become rangers or fighters. Other adventuring vocations are rare; Firbolg monks were completely unknown. About five percent of Firbolgs encountered were shamans.
