Detailed walkthrough
When first approaching the entrance to the Brotherhood of Steel bunker at Lost Hills, Cabbot will greet the player in an unusual manner. If asked about joining the Brotherhood, he explains that anyone who wants to join the Brotherhood must first complete a quest, apparently on orders from the High Elder. The quest involves retrieving a holodisk from the 'ancient order'.


 * If the player's Intelligence is 3 or less, they cannot complete this quest, as they can't ask Cabbot about joining. Darrel, the Paladin standing to his left, will laugh at the player, stating that the Elders instated a minimum I.Q. requirement for new initiates. However, he will point the player to the Glow, telling them to search the facility if you want to obtain some better arms. He will also gift them some Rad-X, warning about the high radiation levels present there.
 * Even if the holodisk is retrieved, the player will not have the option to give it to Cabbot.

The surface and the underground facility at the Glow are both highly irradiated, so anti-radiation chems are a necessity.
 * Rad-X can be bought from Vance, or from Mitch in the All-In-One store in the Hub. Alternatively, 6 of them can be found in an ice chest in the Followers' library.
 * RadAway can also be bought from Vance. It's useful, as the player might accumulate some radiation before you get the chance to use Rad-X. Use caution, as it is possible to become addicted.

Rope is also necessary to get inside.
 * There are two in Shady Sands:
 * Seth possesses a rope that can be bartered for, or stolen.
 * One can be found in the eastern portion of the town in the house next to the crops.


 * Mitch has 5 ropes to trade for.

Once the player has all the supplies, travel to the Glow. The player needs to take 2 Rad-X as soon as they arrive to reach 100% resistance to radiation (each yielding 50% resistance). Without these, it is very easy to die from radiation poisoning. They then need to use the rope on the metal beam protruding into the crater to descend down into the facility.

The holodisk is located on a corpse wearing power armor. The player needs to circle the level to get it. Once it is in the player's possession, delivering it to Cabbot will complete the quest.

Rewards
