Hadar, also known as the Dark Hunger, was a star-like Elder Evil from the Far Realm who had taken a place among stars of Realmspace. Unlike normal stars, Hadar didn't have a fixed place in the sky but instead danced and wavered across Realmspace.
Hadar was a cinder-red star, barely visible in the night sky.
Hadar was usually sought out by some warlocks to make a pact with it. Neogi were specially adept to seek out pacts with it and the other Far Realm-infested stars. To those few Hadar bestowed the ability to use the spells arms of Hadar, hunger of Hadar, as well as brood of Hadar.
