If I am dead there is no death,
But nor would life exist,
No universe would ever be,
No water, earth, or stone.
No riddle ever spoke or read,
My binding spell escapes,
Unconquered by the darkness yet,
Though light escapes my fate.
I appear in the fire’s flames,
Lurk in the dragon’s den,
The number of a man acclaimed,
Within me there resides.
I am really not sure if this riddle is too easy or too hard, I'll leave that to you to decide.
I am not mentioned in the poem.
Now that is has been solved, something which went unnoticed (Spoiler!):
The answer also appears in the last word of every line.
