The Synchronous Orb is an organelle within the body responsible for one's worldview or outlook. When you meet someone with whom you have an immediate and implicit affinity, whom you instantly take a liking to and with whom you get along effortlessly, you are said to have "synchronous orbs". Thus the orbs form the basis of friendship.

When two people who share synchronous orbs are also lovers, they feel like soulmates. Nothing can come between such a pair, and the strength of their devotion to one another is the stuff of legends.
