Klaha - Environment: By standard Imperial protocols, Klaha just barely falls within the range of habitable systems. Its location is well within the temperate range for its star type, the atmosphere contains enough oxygen to be breathable, and surface gravity is well within tolerance range for Human civilisation.The toxicity of its atmosphere and geology, the scarcity of water, and the extreme weather patterns due to its constant geological activity scarcely factor into that analysis. The world's mineral wealth more than offsets the challenges imposed by the environmental issues.Establishing more than a foothold, however, could be extremely challenging for any potential colonists. The toxic nature of the atmosphere would require any Humans who lived on Klaha to constantly wear rebreathers or remain within an environmentally-controlled space.More than eighty percent of the planet's surface is covered by dunes made up of sand and light-weight volcanic ash, which are poorly suited to large construction efforts. Water is a precious commodity; what little surface water exists is heavily contaminated by heavy metals that are toxic to Humans.Most of the remaining surface is made up of mountainous regions, which also require careful planning and construction for any large-scale habitats.Clearly, Humanity is not the only species that has found the planet's environment challenging. There are few indicators of any native life on the planet. The earliest surveys of the system found only trace evidence of single-celled organisms.Even this evidence was initially inconclusive, and suggested that Klaha might simply be too dangerous for life as we know it to survive its environs.Later research, also dating to the Jericho Sector's golden age, showed evidence that more complex forms of life might have been present in the past and suggested that some might yet remain. Notably, all conclusions were inferences made based upon secondary data.No complex life forms were ever identified or recovered. Much more recently, Watch Station Klaha has observed movement patterns upon the planet's surface. A number of these observations are in locations distant from the Mount Pride complex.This data is far more suggestive of a large group of herd creatures moving across the world's surface than of simple life forms. It is improbable that such a large group of creatures could spontaneously develop, but these recordings are the earliest evidence of surface life.More precise information could offer far greater details and might present a credible explanation for this. However, due to Klaha's volatile atmospheric conditions, these observations would need to be made by agents sent to the planet's surface. The Heretek presence also represents too significant a threat for this to be a viable option at this time.A previously unknown life-form, particularly present in substantial numbers, most strongly suggests the presence of a sentient species intruding upon Klaha. Among known xenos, a Tyranid assault might be the most likely explanation for such movement, but Watch Station Klaha has recorded no evidence of any Tyranid biocraft within the system.Alternatively, it is possible that some native organisms might have hibernated beneath the planet's surface for thousands of standard years. If this is the case, it could be a survivor from an ancient and very different geological age.Alternatively still, it might be that the specimens maintain an unusual developmental cycle that requires an extended period of isolation.In any case, the presence of life could be an indicator that Klaha might have untapped organic mineral resources in addition to the known heavy metal ones.Such precious commodities would only enhance the world's value for mining and manufacturing purposes. Should this information reach the Achilus Crusade, some of its hierarchy might be interested in establishing a fortification on the world.As Deathwatch members prefer to keep the locations of their Watch Stations secret from the greater Imperium, attempts to study the system might be opposed by Kill-teams.
