The disaster relief outpost was apparently set up during the New Plague before the Great War by local disaster relief workers. A terminal located in the tent on the far right (with the shore to your back) reveals the government was using the Plague as an excuse to register civilians. Humorously, the fourth symptom of the plague was listed as "New Ideals, such as socialism", obviously to register possible communists, undercover spies, and so forth. The "Presidential Fitness Program" states the New Plague is commonly referred to as "social disease" and advocates isolation, stating that people should protect themselves by staying home to "enjoy a novel or home-cooked meal", limiting social interactions such as:
Ice Cream Socials
Cruising Main Street
Attending Fairs or Festivals
Furthermore, people were told that if they suspected they were infected, they should contact the disease control center for quarantine immediately.
The terminal reveals the social workers' resentment for being stationed in Point Lookout, claiming they were there to help people but that the people in the town were apathetic and the locals in the swamp were hostile. One of the workers, Victoria, was attacked when she ventured into the swamps to try to make contact with the locals. She was knocked out and didn't remember anything after blacking out (but no supplies were stolen from her truck). After that, the workers no longer dared to venture into the swamp.
The tents had been wrecked when they were discovered by a traveling Missionary, Marcella. She reassembled them, and uses them as a "base camp" for spreading her message to Point Lookout. Her tents are easy to find as soon as you leave the Duchess Gambit, just head back down the coast from where you disembark, heading away from the smoking mansion Tobar tells you about.
