From that time, many bizarre species evolved and clawed their way to supremacy or were eradicated from the food chain. The falchion soared above the contest of evolutionary fitness due to an early bond with metallic alloys that were incorporated and reproduced through RNA, making it the result of a genetic virus that turned into an advantage for the new strain of avian predator. The wingtips are hollow, so as to reduce the flight weight, but the tail is solid and acts as a balance rudder for dives.
The edge of the falchion's feathers--particularly on the wingtips and tail--have become hard and sharpen themselves over years as a result of flight and movement. The older a falchion grows to be, the more brittle but razor sharp the feathers become. Elder falchions are the most fierce and deadly, until one day they enter such a heated frenzy that their razor wings cut the animal to shreds with self-inflicted lacerations.
Mostly solitary creatures, they hunt alone but live in mating pairs for the purpose of raising young. Each dozen mooncycles the falchion produces one offspring whom they protect fiercely. Valley with dense populations of the birds become gauntlets of blades during the spring of new births. They prefer to make their nets out of scrap metal, and are known to raid junkyards to procure nest materials. If an early demise befalls the parents, other falchions will adopt and raise the abandoned youth as their own.
Even though they possess formidable power both from their blades and from their strong bodies made brawny enough to handle the weight of metal, they are largely scavengers and use their might to fend off other weak carrion seekers. Conflicts with mortalfolk are rare, and usually come as a result of entering a nesting ground or unwarranted provocation.
Falchions are coveted for their naturally grown blades. With the ability to produce weapons mostly limited to what can be scavenged and augmented from the old world, these naturally honed swordlike feathers are often used by mortals as weapons. The blades of the wing are hollow and light, through durable, and the tail is a thick metal ideal for outfitting spears as spearheads. Older falchions who have died do not make suitable weaponry, and their blades have grown to brittle. A few have tried to capture and raise younger birds to harvest their feathers, but the specimens do not grow bigger and their blades do not sharpen without freedom of movement. For this reason, hunting and poaching scissor hawks can be a lucrative though deadly trade.
Domesticating is possible, though rarely performed. The falchions are fiercely protective of their young, and any attempt to remove the one annual birth from its nest will often result in painful death from blood loss. For this reason, if one aims to acquire a nestling before the imprint stage of maturity occurs, both parents must be subdued or killed. Even then, some newborn falchions may die prematurely, as the methods to raise one remain largely unknown. If able to be trained though, the strength of one falchion can match that of a score of men. Thus, a falchion falconer is considered to be a strong and deadly ally or enemy. Many rich merchants and warlords constantly seek one as a show of their prowess. Greed for harnessing nature's strength has therefore set mortals and the falchions and dire odds with one another.
A falchion known as "Metal Reaver" or "the Bloodhawk" has surpassed the average lifespan of a scissor hawk, by as many as two or three times. It is rumored to be the still-living companion of Thallos from the legendary falchion falconer pairing of Thallo'steel, driven mad by his master's death.
While most falchions will succumb to their own prowess in a fury of blades, the Bloodhawk lives on just as strong if not stronger. The plumage of it's wings is a dark crimson colored, told to be dyed from the blood of killing one of every living beast. More than myth, there have been known sightings of this Metal Reaver--from great distances--and it is not known whether there is one bird, or if there could be numerous elder falchions to reach this state. The sightings are uncommon enough that no definite answer can be made. as mentioned, falchions grow in ferocity and boldness as age increases. Without death consuming this rage of metal feathers, the strength and savagery of this legendary beast continue to soar. Thought to be unable to be killed, Metal Reaver has an almost religious context surrounding it, with some crazed prophets in tin foils hats proclaiming it to be a returned god of metal from the old world, here to continue to wreak havoc for past grievances. The truth remains unknown.
