The visitor gives Cormac the branch and leaves. For a year Cormac uses the enchanting music to deal with every problem in his kingdom. Instead of listening and dispensing justice, he just shakes the branch.
In one year the stranger comes back for the first installment of the payment: Cormac's daughter.
The next year, he takes his son.
Then his wife.
Cormac is left alone. He uses the branch to dull the pain, but he eventually realizes the mistake he'd made, swapping people for easy magic.
