Thirsty?

Darkness their veil
The thirst their bane
Shadows and silhouettes
Murmurs of regret
For shunning death
A taste of immortality
Is all it takes
To grab the chalice
Of ruby red
And drink
Insatiable.

Watch your thoughts
Keep sharp your eyes
As the shadow draws near
You won't know what hit you
Or whence it came
Greedy glint from the darkness
Then the pain
Sharp, then dull
Until the realisation
That it won't come again
Then you'll pray
For death
The release
From this curse
Until the smell of blood
Crosses your nostrils again.
