Elemental Plane of Fire

The Elemental Plane of Fire is one of many Planes of Existence in the Critical Role universe. It is connected to Exandria in the Material Plane with at least a few rifts, the best-known of which has been tended by the Ashari for centuries.

The Portal in Pyrah
In the region of Othanzia, there is a portal called the "Rift of Flame" that connects the Material Plane to the Elemental Plane of Fire. Long ago, the druids of the Fire Ashari established an enclave, called Pyrah, around the portal. They guard it to maintain balance and protect the world from the energies and elementals of the Fire Plane.

The City of Brass
The City of Brass is a large settlement within the Plane of Fire. It is populated primarily by those who are native to the Plane, such as efreet, although humanoids from the Material Plane are not uncommon. However, the city has a very prominent slave trade and those humanoids often end up becoming enslaved.

The guards of the city are a group of efreet known as the Illuminated. They enforce a strict curfew, and anyone found breaking it is put in chains.

Within the city is a building known as the Embassy where ambassadors from the Nine Hells are located.

The Sea of Fire
The Plane features a sea of molten rock and there are "aqueducts" channeling the lava from the sea through the City of Brass. The City of Brass also has naval grounds on the coast of the Sea of Fire.

Planerider Ryn's Study
The Mighty Nein used a Plane Shift scroll gifted by Planerider Ryn to Yussa Errenis to reach a cavern used by her as a study or library. It was guarded by a fire elemental.

Thordak Banished to the Plane
When Emon belatedly realized that the rumors of a great red dragon were true, and that Thordak was a threat, the Arcana Pansophical devised a trap that would banish him to the Elemental Plane of Fire.

During his 15 or 16 years in the Plane, Thordak mostly stayed over the Sea of Fire.

Keyleth's Aramenté
In, Vox Machina entered the Elemental Plane of Fire to help Keyleth complete the Fire portion of her Aramenté. Cerkonos provided a challenge for the group to pass, which they did, but not without finding and barely hiding from a colossal red dragon, later revealed to be Thordak.

Sealing the Breach
When the Chroma Conclave freed Thordak from the Elemental Plane of Fire, they created a breach between that plane and the Material Plane through which many elementals were able to escape and wreak havoc. Many of the Fire Ashari druids were slain or injured. Vox Machina, with the help of Gern Blanston, aided the Fire Ashari in sealing the interplanar rift.
