The next stop on their survey mission was the aforementioned class M planet. The system itself was quiet, with no signs of recent warp trails, mysteriously dead Borg cubes, or anything else untoward. The planet itself was only recently class M; plants were just starting to climb out of the ocean onto the land; the only local vertebrates were still in the oceans, which themselves were so full of CO2 that they were not only acidic, but could make a fairly decent soda. The atmosphere was dense and warm, but the planet was far enough from the local primary that even at the equator the summer temperatures rarely peaked over 80º, and the thick atmosphere meant that the arctic circle rarely drifted below 40º. All in all, it was a temperate, unexciting planet, with large oceans, long beaches, an no native predators.
It was only after Magellan entered a high orbit that any potential problems reared their heads: an obvious shipwreck at around 40º latitude, solidly in the temprate zone. It was "recent", in the sense that it occurred in the past ten years. The ship, which seemed to have survived its impact surprisingly well, as if its beaching were intentional, was in remarkably good condition, and seemed to be surrounded by a modest settlement- perhaps 200 individuals, based on the size and shape. There was no distress signal, nor did was there any response to attempts at communication. There was evidence of farming; the settlement itself was composed of small huts. Until a vessel entered orbit, it was small enough to be invisible.
That was the only hazard on the planet's surface. There were no other signs of technology, and no sign that the settlement ever strayed terribly far from the large freshwater lake that they surrounded.
"Given what we can see," Dekospos said during the requisite briefing, "I suggest that we start cycling crew out for leave on the opposite side of the planet from the ship-wreck, while a security detachment investigates the settlement. They appear to be marooned, but I have no intention of kicking over a hornet's nest if it's avoidable. The goal is to confirm that they are no sort of threat, and see if they need any sort of aid. Questions? Suggestions? With any luck, this will be a bit of a much-needed vacation for everyone."
