Law of Surprise

The Law of Surprise is a custom as old as humanity itself. The Law dictates that a man saved by another is expected to offer to his savior a boon whose nature is unknown to one or both parties. In most cases, the boon takes the form of the saved man's firstborn child, conceived or born without the father's knowledge

Law of Surprise... it's something we invoke at times, but rarely. Usually we just take gold.
