The Beyond

First appears in: The Death Edge

The Beyond (also referred to as the "great beyond") is the vast expanse of outer space into which the ancients scattered the planets that act as pieces of the Defense Mechanism. It represents the uncharted depths of the universe far from Valaralda. During a vision of his past life as Tarathiel, Trey recalls explaining the ancient creation of the machine: “I wasn’t here during the Great Awakening, but they built something way back then. A Defense Mechanism. Then they scattered it into the Beyond".

Later, when Lashel corrects Trey's flawed translation of Ancient Eglarian texts regarding Thangail Band (the shield prison), the true text reveals the fate of the planetary system: "The prison trees were made, a prison to shield them from us. Edrafen was made to open it. We moved the two planets far away from us, into the great beyond". This confirms that Earth (Mar) and Eryn were cast into the Beyond to hide them from the destructive entity known as Guruthos.
