The elder brain is a huge, fibrous mass of cognizant brain tissue covered with writhing feelers. A single elder brain floats within the depths of a briny pool found at the center of its illithid community. An elder brain’s prodigious psychic abilities cause it to pulsate and glow like a windblown ember, charging its gray matter with vitality and purpose. This vitality allows it to remain active long after the bodily deaths of the individual mind flayers whose brains were harvested to engender it.
— D&D Monster Manual


The Elder Brain is the final stage of the Illithid Life Cycle- all Illithid minds are deposited into the brain upon death, strengthening it. It is treated as something equatable to a god for the Mind Flayer society.
