Fires in the Sky

 is a quest in the Fallout: New Vegas add-on Dead Money.

Quick walkthrough
In this quest the player is told by Father Elijah to send each of the three temporary companions to three different locations. Once you've completed report to Elijah. If you choose to bring God instead of Dog, you will have to convince him to trust you. Once you do, he tells you that he requires meat from two Ghost People to keep Dog "in the cage". At this point, two Ghost People will spawn on the map and you will have to go hunt them down. Bring him the meat and he will do his part of the mission.
 * There may be a glitch at the point where Dog must wait at the Salida del Sol switching station, but a simple solution is playing back the 'Dog Command Tape' and getting God to do work the switches. There will be no consequences, but watch your speech choices.

Detailed walkthrough

 * When you start this mission you will have to make a choice between convincing God to follow you, or to use the voice clip of Elijah to turn him into Dog and taking the easy option to follow you.
 * Once God/Dog is your companion, head east from the fountain and follow the street signs that direct you to the Salida del Sol South.
 * Fight your way through to the switch station and here you can either lock Dog in to force him to operate the switches or you can convince God to perform the role.
 * With Intelligence 7 you will be able to rationalize with God. Don't turn him into Dog and he will trust you. At the switches he will agree to stay behind if you have passed the Intelligence check. Read the schematics next to the switches and tell him you'll be able to walk Dog through the procedure. He will agree.
 * Note: If you have less than 7 Intelligence then you can still convince God, although will require you to hunt two Ghost harvesters for meat to stop Dog coming back. Once you have persuaded God to wait in the switching substation the quest is complete.

Bugs

 * When recruiting Dog and God, a glitch may cause you to be unable to talk to God/Dog and in turn be unable to send him to the fountain where Father Elijah waits. Father Elijah then continues to ask why you have come without finding all the companions, and also you won't complete the achievement for recruiting all of the Dead Money companions even if you actually have. Consequently this also makes you unable to complete the DLC and you will have to restart your game or load a save game prior to visiting the Sierra Madre.
