Chroma Conclave

The Chroma Conclave was a faction of five chromatic dragons confronted by Vox Machina. The blue dragon, Brimscythe, was defeated pre-stream; the remaining red, green, white, and black dragons were major villains over the course of Arc 3 in Campaign 1 (episodes through ).

A union of convenience
It was Raishan and Thordak (though mostly Raishan) who brokered the idea of the Chroma Conclave. During Thordak's imprisonment in the Elemental Plane of Fire, he was approached by Raishan, an ancient green dragon who was cursed with a horrific disease that was slowly disintegrating her. Thordak claimed to know of a cure, which he promised to share, but if only Raishan would release him and help conquer the city of Emon. Raishan proposed the idea of the Chroma Conclave — an alliance of powerful chromatic dragons including Brimscythe, Umbrasyl, and Vorugal.

The plan was for the five dragons to work together to wipe out the controlling society of Tal'Dorei. Of greater concern to the Conclave was the immediate threat of Draconia, as the Dragonborn civilization had been keeping close tabs on many (if not all) of the Conclave's members. After Draconia and the Tal'Dorei government were dealt with, the continent of Tal'Dorei would be divided up among the members. Both Brimscythe and Thordak wanted Emon for themselves, but Brimscythe was killed before the claim could become an issue.

Brimscythe
The young blue dragon Brimscythe had infiltrated the Tal'Dorei Council, taking the guise of a human named General Kreig and the position of Master of Law. As General Krieg, Brimscythe thwarted an assassination attempt against Sovereign Uriel Tal'Dorei II in early 810 PD, which was carried out as part of a demonic incursion. During their investigations into this incursion, the adventuring party called The S.H.I.T.s, later known as Vox Machina, investigated General Krieg's house and found a teleportation circle leading to Brimscythe's lair in the Cliffkeep Mountains. Inside the lair, General Krieg appeared and revealed his true form as the blue dragon Brimscythe. The dragon fought Vox Machina and nearly devoured several members of the group, but was eventually slain by Vax'ildan. In his death throes, Brimscythe thrashed about the cavern, knocking down several support pillars and causing the roof to collapse. Vox Machina barely escaped back through the teleportation circle. However, the group noticed four obsidian orbs on a cavern wall that the Chroma Conclave seemingly used to communicate with each other. One of the orbs was touched and a massive, scaly eye appeared within it. As it appeared, a voice called out for "Brimscythe". The eye then noticed Vox Machina, and the voice said, "Intruders. I know your face now. He is a fool, and so are you, insect." All four orbs simultaneously cracked, and became inert.

Ultimately, Brimscythe's death was convenient for the Conclave, as the overly ambitious blue dragon was vying for control of Emon. Thordak would not have allowed that and was planning to kill the younger dragon himself.

Thordak's release
In 806 PD, Raishan infiltrated the Fire Ashari village of Pyrah, built around a portal to the Plane of Fire. There, she took the guise of a young humanoid girl and was accepted into the Ashari. She spent her time there researching the Elemental Plane of Fire. In order to facilitate Thordak's escape, Raishan formed an alliance with a number of fire giants ousted from the City of Brass. With their help, she encased a bit of the Fire Plane, called the Ember Seed, into the soul anchor in Thordak's chest, allowing him to leave the Plane of Fire. She planned to wait until a Celestial solstice to enact the plan for Thordak's escape, but seeing his deteriorating mental state due to the Ember Seed now embedded in his body, she went forward on 20 Duscar 810 PD, Winter's Crest. Raishan widened the rift to the Plane of Fire in Pyrah and Thordak tore through the rift, razing Pyrah as he went. Leaving devastation behind, he and Raishan rendezvoused with the other members of the Conclave and set their sights on Emon.

Chroma Crisis
The Chroma Conclave invaded Emon, destroying most of the city. The city was subsequently occupied by Thordak, who claimed the surrounding Bladeshimmer Shoreline as his domain and took the Cloudtop District in Emon as his lair, demanding abject obedience and tribute from its citizens.

Umbrasyl attacked Westruun and the Dividing Plains and allied with the Herd of Storms, but made his lair in Gatshadow, draining their valuables from the remaining residents. Raishan did not claim new territory during the Chroma Crisis, but her lair was within the Rifenmist Jungle and later on the Island of Viscan. Vorugal and the Conclave destroyed Draconia (considered to be a priority target because they were tracking the dragons' movements) and Vorugal then made his lair among its ruins.

Aftermath
Thordak's Crater in the Cloudtop district became a breeding ground for cinderslag elementals, and the expanse of farmland to the east of the city was torched by the dragon and corrupted by his elemental energy, unable to regrow. This land became known as the Scar of the Cinder King. In order to combat this, the Tal'Dorei Council reached out across the Ozmit Sea to the Fire Ashari. While they were still recovering from their own decimation at the hands of Thordak, the Fire Ashari obliged and set up a base, Flamereach Outpost led by the firetamer Lorkathar, to help contain and eventually heal the Scar. In 842 PD, over thirty years after the Chroma Conclave's attack, the Scar had yet to entirely heal.

Legacy
During the year break, Percy commissioned Senokir to make "hero's crests" for each member of Vox Machina. The crests were featured the dragon scales of the Chroma Conclave, jeweled with gemstones. Percy also commissioned one crest for Tary, but it was made excluding the dragon scales.

In 15 Misuthar 812 PD, Scanlan began to write down his version of the epic adventures he witnessed with Vox Machina, from their first meeting to saving the world and everything in between. The book was called In the Belly of Dragons, referencing the group's battle with Umbrasyl.

As of 843 PD, there is a spa called the Chroma Dawn Cave in Kymal arranged to look like a dragon's lair, with five rooms each themed after a member of the Chroma Conclave.

Members

 * Raishan, the Diseased Deceiver (ancient green dragon, killed by Kerrek, Vox Machina, and their allies)

 * Vorugal, the Frigid Doom (ancient white dragon, killed by Vox Machina and Raishan)
 * Brimscythe, the Iron Storm (young/adult blue dragon, killed by Vox Machina)

Trivia

 * Raishan is the only member of the Chroma Conclave to have been defeated by a guest character, Kerrek; her four colleagues were killed by members of Vox Machina: Vax'ildan (Brimscythe and Thordak), Vex'ahlia (Vorugal), and Grog (Umbrasyl).
 * Raishan is also the only member who survived the episode that shares her name, whereas Umbrasyl, Vorugal, and Thordak were all killed in their respective episodes (, , and ).
 * In Westruun, there is a statue of its founder Palest Westruun named after Umbrasyl, "The Black King". It was erected on an anniversary of the city's freedom from Umbrasyl. Both the city and the statue were blessed by a High Priest of the Lawbearer and when the city is threatened, the statue will legendarily animate into a stone golem to defend the people of Westruun.
