Quest Note
For more information about what you can see and do in the
Citadel and
Little Lamplight, please refer to their location entries.
Walkthrough
When you enter the
Citadel, you'll witness a conversation between Dr. Li and Elder Lyons. Dr. Li will tell the elder about what just happened in the
Jefferson Memorial, including the attack by the Enclave and the death of your father, and then she'll come up to you and tell you to seek out Scribe Rothchild, who you'll find in the laboratory.
Scribe Rothchild won't know where to find a G.E.C.K., but he'll suggest that you access the Vault-Tech terminal in the library (in the A ring) and check there. If you read enough of the files, then you'll discover that a G.E.C.K. was assigned to
Vault 87. When you relay this information to Rothchild, he'll show you the location of
Vault 87 -- but he'll also point out a problem. Apparently, the entrance to the vault is so irradiated that it can't be used, but he'll speculate that you might be able to find another way into it via the Lamplight cave system.
When you arrive in
Little Lamplight, you'll be stopped at the front gate by a kid named Mayor MacCready (#1). He'll tell you that he doesn't trust "mungos" (adults), and so, unless you have the Child at Heart perk or pass a speech check, he won't open the gate for you. To get him to open the gate, you'll have to complete the main quest
Rescue from Paradise, which will involve you going to
Paradise Falls and rescuing the child slaves Sammy, Squirrel, and Penny.
Note: If MacCready doesn't require you to complete
Rescue from Paradise, you can still trigger that quest by going to
Paradise Falls and talking to Sammy.
After getting inside
Little Lamplight, if you ask Mayor MacCready about
Vault 87, then he'll tell you that there are two doors leading to it, but that one of them doesn't work. This will give you two ways to proceed.
Route 1: Murder Pass
For this route, keep talking to Mayor MacCready, and tell him that you'd like to enter
Vault 87 via Murder Pass. This will cause MacCready to travel north to the back gate (#3) and open it up for you. With the back gate open, you'll be able to access Murder Pass (via Exit C).
Inside Murder Pass, you'll encounter lots of super-mutants and traps, but you'll also find lots of supplies and skill books (#4 and #6), so you might want to take this route even if you can take the other one. Eventually you'll come to a door leading to
Vault 87 (Exit E), and when you go through it the quest will come to an end.
Route 2: Reactor Chamber Door
After talking to MacCready, you should track down Joseph, who sometimes shows up in the "office building" (#2) next to the front gate (#1), but who otherwise wanders all over the caverns. Joseph is the schoolteacher, but he also knows about the reactor chamber door (Exit D). If you ask him about the door, then he'll offer to power up the terminal next to it, but he'll tell you that he doesn't know the terminal's password.
When you reach the terminal, you'll discover that it only has "average" encryption. If you can hack into it, then you'll be able to unlock the reactor chamber door and enter
Vault 87 immediately. Otherwise you'll have to go through Murder Pass. If you go through the door the quest will come to an end.
