There was a time when Unicorns lived among mortal herds in disguise - they had kept their distance from human beings for centuries, until horse domestication spread from Central Asia all across Europe. Unicorn hunting became a specialty of black magicians; as plants grew wherever Unicorn set foot on and trees flourished wherever they flew over, black magicians came to believe that Unicorn blood possessed the power to bring the dead back to life and grant mortals immortality.

When Unicorns were hunted to the edge of extinction, the last of its kind fled into a half-finished Cathedral, where God had set up a Holy fire barricade, a place for the Unicorn to be nourished, and the power to fight against the Unicorn hunters.

This is later known as the Holy Flame and Devil Fire that engulfed the half-finished Bath Abbey Cathedral in 1137, the first church to implement Unicorns into their ornamental mouldings. No one knows what happened to the last Unicorn or the Unicorn hunters at the end, but few believe they still exist in present times, the former within churches while the latter live among us.

(Holy Flame is a work of fiction. Any resemblance to actual events or persons, living or dead, is entirely coincidental. Bath Abbey and the 1137 fire, however, are very real. It is a Cathedral built to serve as a monastic church in the 7th century, and is now world famous for its unique construction of beige Bath stone, atypical perpendicular form of Gothic architecture and its finest vault in England.)
