Daelkyr

The daelkyr are a fictional race originating in the Eberron campaign setting for the Dungeons & Dragons fantasy role-playing game. Lords of the plane of Xoriat, the Realm of Madness, they are immortal and immensely powerful, and have legions of monsters created by them (like beholders, mind flayers and other kinds of aberrations) at their command. They resemble handsome humans bearing armor and weapons made from chitin and raw muscle.

Like the quori before them, the daelkyr tried to invade Eberron, but ultimately the Gatekeepers, a druidic sect dedicated to protecting the world from aberrations and outsiders, were able to sever the connection between Xoriat and Eberron. A few daelkyr were trapped in Khyber after the invasion was repelled, and they have been trying to get Xoriat coterminous with the material plane ever since. The daelkyr invasion was the main cause of the fall of the Dhakaan empire.

Trapped daelkyr
There are believed to be at least six daelkyr trapped beneath Eberron in the depths of Khyber (Eberron's equivalent to the Underdark). Through the Cults of the Dragon Below, sages know the names of a few of these individual daelkyr.

Dyrrn
According to Gatekeeper legend, Dyrrn the Corruptor is the mightiest daelkyr. Dyrrn is responsible for the creation of dolgaunts and dolgrims. Dyrrn is believed to be trapped beneath the Eldeen Reaches.

Belashyrra
Also known as the Lord of Eyes, Belashyrra is said to have created beholders. It is said to have a chamber within its citadel covered in eyes, through which it can look through the eyes of any living creature.

Orlassk
Orlassk, the master of stone, is said to have made medusas, basilisks and other petrifying creatures. Orlassk's citadel is said to be a giant gargoyle formed from living rock that prowls the depths of Khyber.

Kyrzin
Kyrzin is a prince of slime and ooze who lives beneath the Shadow Marches. Kyrzin has created numerous types of oozes, including parasitic oozes that may control their host or burst from their host's flesh.
