You do not need to fight in this quest. Vaultopolis is free loot and the vault dwellers give you free things. Some rooms are empty, while most give small rewards such as common weapons and caps, the room in which the vaultopolis dwellers might contain better loot.
- "Welcome, friends, to Vaultopolis!"
- "Many seek our sanctuary. Few find it. For we are... utopia!"
- "You are from a vault, no? May yours grow to be as amazing as ours."
- "You are welcome here always. Take these gifts, and our friendship."
