Nasskugel was one of the last planets discovered by humanity along a starway route.

The planet in some ways resembles earth in its very ancient path, with a thick atmosphere and humid surface. At the poles are massive swamps as the planet’s conditions are long past even a technical ice age. Inwards from the swamps there are large oceans and bodies of water going into and breaking up the land; what land pokes through is covered in jungles approaching the equator. The equatorial region is too hot for humans to survive.

Despite the miserable conditions, much of the planet is still habitable for humans, and in '41 SD the first human colony set down. Over the next two decades more outposts on the planet were set up and people turned the planet into a home for themselves. Unique biological specimens were researched, and useful ones were grown, gathered, or hunted by the colonists as a large part of their economy.

However in '63 SD, Nasskugel was invaded by the arweli as part of their wide scale rapid surprise attacks on human controlled worlds. Nasskugel was seen as a stepping stone into the interior of human territory by the arweli, but when they jumped further in from Nasskugel the next human planet in had massed space assets to repel them. The damaged arweli fleet that returned to orbit over Nasskugel could not attempt to attack again, nor could they abandon Nasskugel defense to ensure human ships did not go through it to enter arweli territory.

The arweli ground forces landed to secure the planet and wipe out the humans to prevent them from being a long term threat. Orbital bombardment was held back on as humans were scattered in such low density that it was deemed to be inefficient, and the hot, wet world was seen as a paradise by the amphibian-like arweli who wanted to preserve it.

The human colonists originally put up defenses with the home guard and security forces fighting conventionally to defend the larger, slower floating colony hubs. As arweli ground forces intensified their campaign of extermination, the humans adapted with the military forces shedding helmets and armor and donning multi-spectrum camoflague anti-thermal suits which were like saunas in the conditions but could make them vexing for the arweli to track. The human colonies broke up into smaller groups of living space vehicles designed to move silently in rivers, or walk in swamps just above the waterline. The few remaining large human settlements were permanent outposts built at the bottoms of oceans, originally as research centers, but they had become central command centers.

The pictured helmet was of a type used very early in the conflict when human forces were still wearing old pre-war issued equipment. The one was found in an abandoned outpost on the southern polar swamp. Markings indicate it belonged to someone in the 6/1, or 6th Region, 1st Brigade Guard. The outpost was abandoned in early '65 SD, and it can be assumed it was left behind then although with poor record keeping there will likely never be an answer to who exactly it belonged to or what their ultimate fate was.
