1,100,000 BCE

Around 1,100,000 BCE, the Forerunner Theoretical Boundless' studies brought into her attention a particular star within the Spider nebula in the Path Kethona galaxy. Though she was soon forbidden from further researching this star by the Warrior rate, she continued her studies throughout her long life in defiance of Warrior orders. Eventually, she was prosecuted, her studies were suppressed, and she was sentenced to enter a Cryptum. The Cryptum turned out to be defective, thought to be sabotaged, and thus she died inside. Her death was discovered a thousand years later when the Cryptum was opened. Her body was discreetly disposed of by a small group of her former students and she eventually faded into obscurity, while the entire Theoretical rate was subsumed into the Builders.
