Rheasilvia, The Dreaming City
Drifter: Listen, this Lightbearer you're looking for? His name's Callum Sol. Like I said, he ran headfirst into the Ascendant Plane. Thanks to those Raider friends of yours, there's bound to be a portal nearby. Keep your eyes open.

Ghost: I don't have a mouth.

Drifter: Nothin' kills you quicker.
Ghost: I'm pulling final audio from his Ghost. Hang on.
Shin Malphur: I gave you a chance. Gave all of you a chance. I told you not to follow him!
Callum: You and I are the same. Sometimes we do the wrong thing for the right reasons.
Shin Malphur: Spoken like a true disciple. If you have any last words, now is the time.
Callum: You'll never kill us all.
Shin Malphur: I don't have to. You're killing yourselves.
The sound of a Golden Gun charging and four shots firing from it can be heard in the recording.
Ghost: I think you have some explaining to do.
Drifter: Gimme a minute, would ya?! I'm thinking.
Ghost: You owe us a little more than Glimmer for this.
Drifter: Shut up and bring me everything you found at that grave. You'll get paid.
The Guardian finds a depleted weapon core at Callum's grave.
