Prologue: Briefing
As Master Chief prepared to be launched to the surface of Eridanus II, he thought back to his mission briefing hours ago.
"You are to guard Eridanus II against any Covenant invasion," commanded Doctor Halsey.
"But Doctor, wasn't the entire Covenant wiped out five years ago, and besides, why use Master Chief to protect Eridanus II? Wouldn't it be safer to use the marines?" questioned the confused Cortana.
Doctor Halsey shook his head and answered "No. And Master Chief knows why. Let him tell you later, it is too horrible to discuss now."
A sudden jerk brought the daydreaming Master Chief back to reality. "Prepare for the launch of the escape pod!" A genderless voice announced.
Cortana's cool, clear tone flooded through his combat speakers, "Here we go."
