A coming-of-age story, Forward Unto Dawn follows a cadet, Thomas Lasky, at a twenty-sixth century military training academy as it is attacked by the Covenant, an alliance of alien zealots. Lasky is unsure of his future within the military but feels pressured to follow in the footsteps of his mother and brother. Lasky and his surviving squad mates are rescued by the Master Chief and, after the death of his romantic interest, Chyler Silva, Lasky is inspired by the Chief to take initiative and aids him in saving the remaining cadets.

After stealing the Tesseract during the events of “Avengers: Endgame,” an alternate version of Loki is brought to the mysterious Time Variance Authority, a bureaucratic organization that exists outside of time and space and monitors the timeline. They give Loki a choice: face being erased from existence due to being a “time variant” or help fix the timeline and stop a greater threat.
