Bicorn

Behavior: Bicorns are exceptionally passive creatures that are extremely skittish. Hunted nearly to extinction by both man and otherwise, the species has evolved an unsurpassed sense of smell and hearing. These timid creatures are known to bolt at the slightest indication of almost literally anything within their vicinity. Due to their flighty temperament, these legendary equines have developed physical stamina which is nearly unmatched. Able to run at a consistent top speed of 22 meters per second (49 miles per hour), few creatures can actively keep pace with them as they gallop for hours on end until they are once again isolated from nearly all forms of life. It has never been observed to fight, even when cornered. Instead of combatting pursuers, bicorns will do everything possible to flee even at the cost to their own health such as breaking their own horns, and injuring themselves by attempting to force their way through openings far too small to fit through.

Details: The horns and hooves of bicorns are said to hold immense medicinal properties, legends of poultices and tonics made from the ground hooves, horns, and sometimes even hair are said to be able to remedy even terminal afflictions and ailments. Due to these rumors, it's no surprise that bicorns have become nearly extinct in the modern day, only sighted roughly 3 times per year. Other rumors stir that there are certain entities and organizations that strive to capture specimens for breeding purposes to bolster the species' numbers once again and to grant a boon to medical sciences and research. Of course, along with these rumors come ones of said parties placing literal fortunes upon each captured and healthy creature's head.(edited)
