The Voltmaster Laughing

“Follow the wires.”
These are the first three words that every child in Mirkwood learns.
They look up at the gigantic mains that pass near every village, and down to the substation as the voltage is stepped down.
“Follow the wires, and you will find The Voltmaster.”
He used to harvest his power from the clouds, but with the help of giants and ogres and dwarves, he constructed a dam across The Eternal Falls.
Within, machinery like windmills, but for water, convert the flow into energy.
Precious energy.
The lights flicker, then return.
They say this is The Voltmaster laughing.
