His backstory:
"Moving like a breeze, gliding down the lane,
Harlequin is whistling a melodic refrain,
Harlequin is silent,
Harlequin is bold
And Harlequin never tells what Harlequin is told."
by Ben Ezzell
The Harlequin
He is old. Some people can recall him holding lavish parties as far back as 300 years ago, while there are claims he was one of Veronica Franco's most avid admirers back in 1575, and that he was one of many who actively did their best to make sure she burned at the stake. There are rumors of the First Crusade. Of gifts from the gods of Egypt.
Harlequin neither denies nor confirms.
As for his name, he goes by many but answers to none.
This though is true: He is not a pureblood.
Also true: He is more powerful than most who lay claim to being children of the ancient bloodlines. They let him live because he cares nothing about the politics of the living and the dead. (They let him live because he is too powerful.)
He cares only for dreams. Of stories within the dreams.
His power is such that with a look he can extract a person's memory, to find from them a person's greatest desire, and make it come to life. His power are of the dimension of the spoken word, and how with it, he could warp time and truth, turn fiction into reality.
This man is the Harlequin. Pray that he never glances your way, lest he bring to you his story knife and turn your world upside down.
