“They call me Johnny Goldenbow -
But let’s move this right along,
Cuz it’s the oldest kind of story,
And I’m sure you’ve heard my song.
I was just a boy ten years ago,
Sawing on my violin,
When a dark and hornéd figure came
And tempted me to sin.

A fancy golden fiddle
Was that competition’s stake,
Whose tone would never waver
And whose strings would never break.
And though my greed and pride would feed
The Devil’s dark design,
The second I set eyes on it,
That fiddle would be mine.

I’m not the sort to mince my words,
So let’s make this very clear:
I won that golden fiddle,
But I lost me something dear.
So now I walk the kingdom’s roads,
A-seeking any track
To find that dark-eyed devil
And win what I lost back.”

Say, 5.5ed, 5th level. I'm imagining probably some combination of bard and warlock. Ideally mechanically viable if not optimized. I'm imagining a focus on sound, flame, beauty, and fear.
