Growth-Through-Trial-of-Change

Growth-Through-Trial-of-Change, or simply Trial, was a Forerunner Lifeworker. She was one of the few Forerunners to survive the activation of the Halo Array.

Early Life
Trial was born to a family of Builders. However, she refused to be a Builder and instead became a Lifeworker. Her family rejected her as a result, and she was adopted by a foster family. Her family died long before the Forerunner-Flood war as they were caught in the explosion of a star while they were traveling to another world.

Post Forerunner-Flood war
Trial, serving under the new Lifeshaper Chant-to-Green, was tasked with cataloging humans on the lesser Ark and later overseeing the reintroduction of humanity to Erde-Tyrene. During the process, she personally oversaw the awakening of Riser and the other human specimens on a Lifeworker ship that had survived the destruction of the greater Ark, and guided them to an artificial settlement on the surface of the lesser Ark. The humans would remain there until they were scheduled to be reseeded back onto Earth. Some time after the activation of the Halo rings, she was also present in the trial of 05-032 Mendicant Bias for the AI's betrayal of the ecumene.

Following the reintroduction project, it was implied that she, along with the other surviving Forerunners, took on a great journey with an unknown destination, as they felt they should no longer meddle in the matters of the galaxy.
