Existence defines reality. Beyond it, therefore, naught exists—not even a void. This simple reasoning would be irrefutable were it not for the existence of vestiges. Called forth from nowhere, composed of nothing, they exist entirely outside the rules of reality. They are untouchable, untraceable, and beyond all powers that might attempt to confine or define them. This philosophical conundrum has intrigued sages interested in pact magic for centuries and defied all their theories. Vestiges simply cannot exist, and yet, it seems that they do.
Some scholars say that vestiges are a common myth—they do not actually exist but are inherent in the minds of all beings. Others say they are true spirits—souls cast off into some plane that is unreachable by all magic due to an agreement between the gods. Whatever the truth of the matter, vestiges seem desperate to participate in reality, if only by peering at it through another creature’s eyes. That most binders try to maintain and the cloud of suspicion under which they must work.
