The first being and heart of Adrem, Grand Consciousness. The Unborn Dream slumbers within The Embryo of Self and Other, and it is thought that should The Unborn Dream become to emotional in any way and awaken, Adrem will be shattered, killing Urtholm. A group of Meticem, called The Sustainers, work endlessly to ensure that it is always in a state of calmness, though not content; contentment is thought to kill The Unborn Dream.

Through The Unborn Dream, all other parts of Adrem are woven; from the landscapes to the residents. None are truly aware of what its motives or thoughts are, if any exist. The Sustainers believe it is the collective unconscious of Urtholm and that if it should awaken or die, the world will cease to exist in anyway that is inhabitable.
