I am the bard who sings the song,
Of heroes lost and battles won,
The raconteur 'round campfires sits,
I stir friends' hearts, confound their wits,
The unseen weaver, spinning threads,
My wyrd twists one within them dreads,
I am the scribe, records the deed,
Though no one will my writing read,
The watchful keeper of the gate,
Beyond which bold adventures wait.
What am I?
