Rebirth

Halo: Rebirth is the epilogue to Halo: Silentium, downloadable via Halo Waypoint by entering the code found at the beginning of each chapter of Silentium. The story follows Riser and his arrival on the lesser Ark and later his return to Erde-Tyrene. Days after, a new code was revealed, adding 5 additional minutes to Rebirth, describing the trial of Mendicant Bias after its defeat at the Battle of the Maginot Sphere.

Story
Rebirth describes the reintroduction phase from the perspective of Riser. Having survived the destruction of the greater Ark, Riser and many more surviving humans wake up in a Forerunner ship, overseen by the Lifeworker Growth-Through-Trial-of-Change. The humans - along with specimens of many other species - are relocated on Installation 00, the lesser Ark, where they are watched over by the Forerunners until it is deemed safe to return them to their homeworlds. Among the surviving humans is Vinnevra, who Riser met earlier on Installation 07 during the events of Halo: Primordium. When the humans are eventually returned to Earth, Riser's people are relocated on a series of islands at his own request. Riser meets with the IsoDidact one last time before the Forerunners leave and the humans begin settling in their new home.

A separate audio string accessible via a different code recounts a trial held to Mendicant Bias after the AI's defeat against Offensive Bias. Riser, the IsoDidact and several surviving Forerunners observe as the confined remains of Mendicant Bias' personality construct array are brought to Installation 00. The IsoDidact decides to keep Bias alive as it possesses intimate knowledge of the Flood and can thus be called upon in case of their return. Bias is then entombed in a desert on Installation 00 with only one thought allowed to it: atonement.
