Stone giant

Stone giants are a type of highborn giantkin native to the Material Plane. They are distantly related to goliaths.

Description
Stone giants have gray skin. For giants, they are lithe: they are muscular, but slender and elongated, and they stand between 15 and 20 feet tall.

Tal'Dorei
Stone giants live in fortresses carved from the peaks of mountains. Their greatest stronghold is Skyanchor Citadel, a city hidden within a mountain of the Alabaster Sierras, its halls winding from its deepest roots to its highest summit. The stone giants view physical perfection to be the greatest of all virtues, and are obsessed with both physical appearance and feats of strength. Unlike the lowborn giantkin, who prize brute force over all else, the lithe stone giants see all forms of physical power as worthy.

Sky Queen’s Favor
A quadrennial tournament of prowess called the Sky Queen’s Favor is held in the coliseums atop Skyanchor, and giants from across Tal’Dorei gather to compete in tests of strength, agility, and endurance. Some champions of the smaller races even join, and goliath competitors are not an unusual sight at the Sky Queen’s Favor.

Wildemount
A group of stone giants live in the Penumbra Range of Xhorhas in a stronghold called the Braan (Giant for the "Belly"), led by Soorna, a druid.

Named Stone Giants

 * Soorna - A druid who heads the survivors of a demonic incursion of the Braan

 * Oombad - Soorna's deceased brother

Pre-Stream
Othendin Pass, a valley in the Cliffkeep Mountains, was stone giant territory until the human expansion arrived, discovered rich mineral deposits, and clashed with the giants until the giants were forced to retreat into their caves higher in the mountains to the northeast. The humans then established Fort Daxio to protect their gains.

Chapter 3
On their roundabout way to Whitestone, Vox Machina came across an unnatural formation that Grog immediately recognized as a stone giant fortress, but they found it empty and disturbed. The party soon discovered that the giants had been killed and raised by the Briarwoods to keep watch over the occupied Whitestone. Though several of the zombie giants were killed in the Whitestone Rebellion, some continued to wander the Parchwood Timberlands, tormented by their inability to enter the afterlife and destroying all they saw.

Tal'Dorei Campaign Setting
The adventure hook Bite the Bulette in the sourcebook, set in 812 PD, involves a tribe of stone giants and goliaths returning to a chokehold in the Othendin Pass. The tribe claims to be a druidic order called the Stoneherders that keeps the balance between civilization and nature in the North, and though the presence of Fort Daxio has kept them away for generations, they now need to thin the bulette population that has been slowly rising since the giants were pushed out.

Chapter 14
In 836 PD, the giants of the Braan were forced from their home by a demonic incursion and occupied the nearby Deepriver Mining Camp; the Mighty Nein, called to help get the camp running again, aided the giants in taking back the Braan and removing the cause of the incursion: an Abyssal anchor placed by Vence Nuthaleus.
