Fire giant

Fire giants are a type of highborn giantkin native to the Material Plane.

Description
Fire giants seem shorter than other highborn, but only because of their perpetually stooped posture.

Tal'Dorei
Fire giant civilization's heart is the city-state of Vulkanon, built deep into the magma tunnels that run beneath the heart of the Cliffkeep Mountains. They are masters of the forge, and have been known to occasionally ally with the duergar of the Emberhold to produce some of the finest arms ever seen in Tal'Dorei. Vulkanite weapons are prized by mercenaries across the continent, and are as much a status symbol as they are an excellent weapon. The giants of Vulkanon have long dreamed of empire, and their duergar allies have given them a foothold in Tal’Dorei's darkest depths.

Emon
During their control of Emon, Thordak had several fire giants under their rulership, including Ordis, a female fire giant general who was sent to squash the resistance forces stationed at Fort Daxio.

Wildemount
In the course of their journeys, the Mighty Nein discovered another fire giant citadel beneath the Ashkeeper Peaks.

The setting of the adventure hook Vault of the Fire Giants in the Explorer's Guide to Wildemount, set in Time Line, is a vast dungeon beneath Kravaraad where fire giants have collected treasure since before the Calamity. They have enslaved an adult red dragon to guard their vault.

City of Brass
There was a coup amongst the fire giants of the City of Brass a few years before 811 PD, resulting in most of the giants being enslaved or cast out of the city.

Chapter 6
Vox Machina dealt with fire giants in the City of Brass: during their quest to obtain the Plate of the Dawnmartyr, they got directions from Whaska and ended up briefly enslaved by Juuraiel, but earned their freedom and the armor by assassinating the pit fiend ambassador from the Nine Hells, Ghurrix.

Immediately afterward, Vox Machina fought General Ordis (on an ember roc mount) who was sent by Thordak to crush the remaining forces of the Republic of Tal'Dorei at Fort Daxio, but she died in battle.

Soon after that, in the siege of Emon, Zahra Hydris and Kashaw Vesh took on a pair of fire giants just outside Thordak's lair so that Vox Machina, Lady Kima of Vord, and Jarett Howarth could rush in to slay the dragon. After fighting Thordak and then Raishan, Vox Machina emerged from the lair to find Jarett and (unexpectedly) Kerrek helping to finish off the fire giant guards.

The Mighty Nein, guided by Spurt, encountered a pair of fire giants near an underground citadel as they followed a tunnel carved by Kryn Dynasty forces.
