In Sky Citadel, Quinn would be allowed to access holotapes relating to the situation of the world after The War, allowing him to learn about the Brotherhood of Steel, the Enclave, and their war with one another, as well as lesser organizations like the Book Runners (who also make and sell guns), and what was once Liberty Island and Old Man's Corner, before the Enclave conquered it. He also learned how caps were used as currency, that slavery was common, and that in what markets existed, bartering and bargaining were omnipresent.

Either way, after an unspecified amount of time, a Brotherhood Scribe, female, blonde, and wearing glasses, would come in, and tell Quinn:

"We sent a team to check out where you came from - a Vault, wasn't it? For what it's all worth, your parents are still alive, but are injured, and many of the people there have been slain. If you don't believe me," the Scribe said, "I have pictures."

She then showed him several bona-fide photographs of the near-carnage, before saying:

"Anyway, you're good at Robotics, right? Well, there's a large Construction Droid in our basement with a large crane, a mortar, a laser, and a recycling system. We need you to help calibrate the lasers and mortar....for war."
