You have a natural affinity for rivers, lakes, and the aquatic creatures that live within them. Your bonded item is likely a vial of water from your home or a river-worn stone. You gain the amphibious and water traits. Like all creatures with the amphibious trait, you can breathe both water and air. When resting, you regain an additional amount of Hit Points equal to your level if you rest fully submerged in a spring, pond, or river.
