The Error Pathway is one of the 22 Beyonders pathways, presiding over theft, deception, and loopholes in the laws of the world. Its bearers steal everything: items, abilities, dreams, others' fates, and even moments of time.
The pathway begins with the Marauder potion (Sequence 9) and leads to Sequence 0 — Error, a living exception to the rules of the universe. Together with the Fool and Door pathways, it belongs to the "Lord of the Mysteries" group.
The most famous bearer of the pathway is Amon, the thief with a monocle, whose name Beyonders utter with caution: perhaps he is already listening.
