Ashari

The Ashari are a multiracial people divided into four tribes:  Air, Earth, Water, and Fire. Each of the four tribes live in locations where the Elemental Planes have bled into the Material Plane. The Ashari make it their duty to guard these portals, ensuring that nothing dangerous is able to pass between the planes.

Culture
The Ashari are, for the most part, insular, living in remote areas and not interacting much with the outside world or even each other. Their tribes are made up of a diversity of races, including gnomes, humans, half-elves, and at least one tiefling.

In their role as guardians of the Elemental Planes portals, the Ashari have developed deep connections to their respective elements that influence each Ashari's culture. Their leaders are usually skilled in druidic or other nature magics, but their societies include a variety of professions and classes aside from druids.

The Ashari greet each other with the word "Kaitiakè" (meaning respect, guardian, keeper) as a sort of salute.

Aramenté
Once in every generation, in each of the four tribes, a member is chosen to set out on an Aramenté, or "Noble Odyssey". During this journey, this Ashari member seeks out each of the other tribes and ventures through the portals they guard. Upon completion of this journey, the empowered Ashari member's lifespan increases significantly (Keyleth estimated that she would live a thousand years or more) and becomes the headmaster of their respective tribe. The person chosen for an Aramenté is usually—but not necessarily—a druid or nature cleric.

Air Ashari
The Air Ashari guard the portal to the Elemental Plane of Air in Zephrah. The title given to the headmaster of the Air Ashari is "Voice of the Tempest".

This tribe lacked a headmaster for some years. Keyleth's mother, Vilya, was set to become headmaster and had embarked on her Aramenté, but never returned. Korrin, Keyleth's father, served as acting leader of the Air Ashari in the interim.

After years passed with no word from Vilya, Keyleth finally set off on her own Aramenté. She would eventually complete the task that her mother could not, earning the title of "Voice of the Tempest". Keyleth returned to Zephrah and took her place as headmaster there.

Despite limited interaction with the outside world and with the other Ashari, Korrin led a contingent to aid the Fire Ashari in re-sealing the rift created by Thordak's escape. He also led a military force of Air Ashari providing air support to Fort Daxio's forces during the siege of Emon.

Earth Ashari
Terrah is the home of the Earth Ashari and of the portal to the Elemental Plane of Earth. They are led by Headmaster Pa'tice, the Heart of the Mountain.

The Earth Ashari were the first tribe that Keyleth visited on her Aramenté. She completed a task for them in the Earth Plane. One of the aspects of the task involved the consumption of oloore root tea, which initiates a vision quest for the drinker.

Fire Ashari
The Fire Ashari live in Pyrah and guard the portal to the Elemental Plane of Fire. When Vox Machina encountered them, they were led by Headmaster Cerkonos, the Flamespeaker.

Keyleth, along with the rest of Vox Machina, visited the Fire Ashari as part of her Aramenté. There, they journeyed through the portal to complete a task in the Fire Plane. On completion, Keyleth was given a sparkstone by Cerkonos as a token of her success.

After Vox Machina left, the Fire Ashari were devastated by the ancient red dragon, Thordak, on his escape from the Fire Plane into the Material Plane. Many members of their tribe were killed, and Cerkonos lost an arm. As elementals and other creatures from the Fire Plane began escaping through the rift that Thordak left open, Vox Machina, along with Gern Blanston and a contingent from the Air Ashari, helped the Fire Ashari to re-seal the rift.

Water Ashari
The Water Ashari live in Vesrah, where they guard the portal to the Elemental Plane of Water. They are led by Headmaster Uvenda, the Heart of the Tides.

Visiting the Water Ashari was the third and final task of Keyleth's Aramenté. There, she journeyed with Vox Machina into the Water Plane to collect lodestones from a kraken, nearly losing several members of the party in the process. Upon their return, Uvenda confessed that perhaps the task had become too dangerous and agreed to reconsider it for the future. Keyleth the 9th-level spell Shapechange in celebration of her success.
