Editing Hua Yuan (section)

==Flora and Fauna==
The vast majority, if not all of, the organic life on Hua Yuan is not native to the moon. The large majority of life not only exists within the hive but originates from the fateful flight of the Brimstone. The cattle and hydroponics crop brought by the colonial ship, as well as the vermin, have since undergone a great number of changes since the crash due to the unique environment and through the ingenuity of the Yuanese. 

'''Corpse Lotus''': The sparse few plants within the great hive prefer artificial lighting (if they require it at all), growing around the streetlights and neon signs of the city, in the absence of soil many can take root in anything that was once biological, such as waste or a creature's corpse, if not rooting themselves within the cracks in plasteel and ceramite. The Corpse Lotus is a prime example of such a plant, following the evolutionary path of many plants within the hive and is therefore carnivorous. Large sweet smelling flowers attract vermin to the small berries within. Upon biting them, they're paralyzed and slowly suffocate, allowing the plant to take root in their corpse. This macabre diet is the main mechanism behind reproduction, as released pollen settles within a corpse where it gestates.

This plant has become a symbol of death in the hive, for many times after great carnage a grove of these insidious flowers will begin to sprout. One can mark a scene of great violence past by the density of these flowers in one particular area.

'''Hua Yuanese Rats''': The vermin within Hua Yuan are mostly hairless rodent-like creatures, and at lower levels of the hive, blind. The Yuanese have created pedigree breeds of these things in the imitation of cats, dogs, ferrets and other traditional creatures. While still hairless and vicious, from a distance the resemblance is quite good. Many rats are farmed by pioneering Hua Yuanese and hawked on the street along with whatever mystery meat is available. Regardless of the climes at which they exist the Rodentia of Hua Yuan are all voracious creatures with disturbingly diverse diets, dining upon the daunting diaspora of detritus and deceased, few things in the hive being beyond the  

'''Centipedes''' : Prevalent on the cargo freighter that crashed here, these pest survived with crew, freed from the confines of the ship these pests infest the hive while providing a cheap food source. In the underhive industrial waste has mutated a myriad of breeds of centipede, from those large enough to fight and eat Tyranids to small super rare breeds prized for their hallucinogenic venom.

'''Yuanese Wolves''': Feral Hounds descended from dogs found aboard the original colonizing ship, these animals are a far cry from their ancestors. Hairless, highly territorial, and lacking fear of humans, these beasts stalk the abandoned corridors of the Underhive, feeding on whatever is edible amongst the filth, attacking and eating whatever is dumb enough to set foot in their corner of the mines.

'''Core Dragons''': Centipedes that have grown to obscene length and width due to mutations from radioactive ship cores these "dragons" have become a symbol of territorial dominance and tyrannical power, for not even the most determined of Gangers will set up near a Core Dragon's fiery domain and Exterminators and Enforcers make sure to note dragon dens to avoid their path during operations. These lengthy insects lair in areas of high heat and radioactivity, often putting them at odds with Mechanicus forges and manufactorums. Las weaponry and flamers are ill advised when facing these beasts, as their thick segmented shells are nearly impervious to heat. True to their namesake the core dragons posses what can be described as flaming breath, but in actuality it is simply a defensive mechanism in which they regurgitate the contents of their stomach, which is coated with a highly flammable substance that ignites upon contact with the air. This attack has been noted to be similar to that of Imperial melta weaponry. 

Xenobiologists are fascinated with this illusive creature due to its stunning similarities to the famed and furious Catachan Devil, leading a few to challenge the Hua Yuanese legends about "magically transformed centipedes" and mere altered evolution instead claiming that this may be another possible case of a naturalized Tyranid bioforme.
