Transcript
{Cutscene}

Fade in on a tent pitched on the side of a windy cliff.

''Cut to the tent interior. Spartan Jameson Locke is inside. He notes the holo-table in the center then watches the outside sunset.''

''Locke turns upon hearing footsteps. It is Thel 'Vadam, the Arbiter and kaidon of the Swords of Sanghelios.''


 * Locke: "Spartan Jameson Locke, UNSC. Captain Lasky sends his greetings, and thanks you for your cooperation."

The two look each other in the eye.


 * Arbiter: "ONI... out of the shadows... The spies announce themselves now, Agent Locke?"

The Arbiter turns to inspect some hologram controls.


 * Locke: "I'm a Spartan now, sir."

The Arbiter dismisses his statement with a waved hand.


 * Arbiter: "I know who you are."

''The Arbiter faces Locke again and approaches the table. It activates and displays a projection of Sunaion.''


 * Arbiter: "You were an agent when you volunteered to execute me."


 * Locke: "I saved your life today."


 * Arbiter: "Yet now you hunt another Spartan, the greatest of your clan."

''A rumble is heard as the hologram flickers and malfunctions. A glowing purple sphere arises out of it.''


 * Cortana: "Let him hunt. He'll never find us."

''The holographic sphere retreats into the table. The blast shakes the tent. Dr. Halsey and Sarah Palmer enter.''


 * Halsey: "It's Cortana. She touched every networked device in the camp. She knows the Guardian is here."


 * Palmer: "Locke, that thing's our last shot."


 * Locke: "You have the firepower to get us in there."


 * Arbiter: "Sunaion is the Covenant's final stronghold on Sanghelios."

''The Arbiter begins to leave the tent. He glares at Locke as he does.''


 * Arbiter: "We will move only when victory is assured."

The Arbiter exits, and Locke turns to Halsey.


 * Locke: "Doctor, Osiris will deploy within the hour. Have your plan ready."

Cut to black.

A WHISPER IN THE STORM
{Gameplay}

''The Spartans of Fireteam Osiris are at a cave leading to the Swords of Sanghelios's base camp. An allied Storm Elite stands guard ahead.''


 * Locke: "Guns down, Osiris. We're guests here."


 * Halsey (COM): "Locke, I have a briefing prepared. Given Cortana's show of power, I am reluctant to discuss it over open channels."


 * Locke: "Understood, doctor. We're on our way."

Speaking with Halsey
''The Spartans approach a balcony where Dr. Halsey is overlooking the camp. A hologram of a Forerunner construct is by here, and an Unggoy Storm strolls past. Halsey waves her arm to catch their attention.''


 * Halsey: "Over here, Osiris. I have located a means to activate the Guardian."

Locke speaks to Halsey.


 * Locke: "Osiris reporting in, Doctor Halsey."

Halsey gestures to the hologram.


 * Halsey: "This is a Constructor, a Forerunner tool I can use to interface with the Guardian. Constructors were ubiquitous in Forerunner facilities. These hills are riddled with support stations for the Sanghelios Guardian. Palmer has the coordinates to one such station. Finding a Constructor there should be simple."

Regrouping with Palmer
Palmer is standing by a Pelican docked by a cliff.


 * Palmer: "Ready when you are, Osiris."

If the player agrees to step aboard.


 * Locke: "We're ready, Commander Palmer."


 * Palmer: "Okay. Let's go."

''The Pelican activates its thrusters and takes off. It flies past several enormous statues of Sangheili heroes and heads for the mountains ahead.''

Level ends.

Glitches
If a player jumps off the edge of one of the cliffs and falls to their death, their corpse will go through the rocky sides of the cliff and disappear.

Easter Eggs

 * A singing Unggoy can be found on a ledge in the level. If spoken to, he will explain that he heard the song from a human prisoner.
 * A Sangheili and Unggoy called Dimkee Hotay can be found on a ledge admiring the scenery. If the player waits around them for a bit, the Grunt will begin to comment on different aspects about the Halo franchise rather humorously, including the home planet of the Brutes, the Master Chief's tendency to be unstoppable, and the honor code of the Elites. The Elite will simply grunt back in reply.
 * There is a piece of rock in the cliffs of the level that resembles a human face. It can be seen above the Arbiter to the right of the singing Grunt.
 * An Intel audio log can be found in the level describing interspecies affection between Sangheili and humans. The log is of the Sangheili Vel 'Trokaik reciting a love poem about Sarah Palmer, before being humorously interrupted offscreen by a Grunt.

Miscellaneous

 * The checkpoint named "A Whisper in the Storm" has the same name as the first checkpoint as the Halo 2 level "The Arbiter".
 * The Elite who is fixing the Banshee can be spoken to, and will have different dialogue depending on which member of Osiris speaks to him.
