That's Adytum. It's a slave labor camp run by a group called the Regulators, but they tell everyone it's a "town". They come here and take our people to work them until they die. Then they come and take more of us.
After giving the Blades the weapons, the Vault Dweller will be offered by Razor to crush the Regulators. The player may choose to join them or handle the Regulators without the aid of the Blades.
In any case, the Vault Dweller needs to go to Adytum and kill all the Regulators, their leader and Jon Zimmerman himself. If the quest is completed with the aid of the Blades, the Vault Dweller will recieve a reward of 1500 XP. If it is completed alone, though, the reward is lessened to 500 XP.
Should the Vault Dweller delay the attack, in order to speak to Zimmerman again you must directly select the dialog option, Razor replies that this may not be a good idea.
After choosing the above dialog option, entering Adytum, and returning, Razor will have disappeared. None of the other Blades react to this, and it is impossible to launch the Blades' attack on the Regulators. After eliminating them single-handedly, however, Razor reappears in the Blades' hideout, implying that she fled the area to escape Regulator reprisal.
Named characters, such as Miles, Smitty and Lorraine, can be killed by Regulators during the attack. 2 Regulators are located in the same room with Smitty and thus he is often killed quickly.
