Vampire

It was hot and cold
sometimes new and always old
I was young and bold
My soul had been sold
It was the trill
of the devil's kill
It is the wound that won't heal
and he always comes against my will
I am a creature of the night
I always cause such a fright
and there is a legend about my bite
but with my race, it's alright
I am the Vampire
and I never tire
My throat is continuously on fire
So is this what they all admire?
