This story is set during the High Charity mission from Halo 2, as the Flood attack on High Charity reaches its climax. Although, since the story takes place before the Forerunner Dreadnaught has separated from High Charity, I believe this story is best read before the High Charity mission.

Where to read: The Volume II edition of Halo: Evolutions that this story was included in is now out of print and unfortunately it was excluded from the 2019 rerelease, which is the only one now available digitally and in print. Therefore, this story is now only available in print via preowned copies of Halo: Evolutions (Volume II).
