Be careful when promising your firstborn! Make sure you stipulate your first born human child, blood of your blood and flesh of your flesh. Otherwise the fae with whom you made the fateful arrangement might one day come for your first novel, your first painting, your first album. They are wily ones who find even the smallest loopholes in an agreement; if that contract isn’t airtight, it won’t matter if you never have a child in the traditional sense. On the day you complete your first and most precious creation, no matter what form it takes, the fae will come knocking. Will the bargain have been worth it when they leave with the product of your sweat, blood, and tears?
