Charm for a Pencil

From dark, inchoate chaos, 
Summon now, ye wand, 
Words worthy of a poet 
As I wave you with my hand;

Or else if what is wanted 
Is magical persuasion, 
Then subtlety or bombast 
Befitting the occasion; 

If art, then render pictures 
Enchanting to the eye;
If fairy tales, then fictions
As real as you and I.
