The Sigil-Ridden Navigator
The Sigil-Ridden Navigator: a poor soul who made a deadly mistake on the last ship he worked on, which indirectly costed him his memories.
The ship's captain was heading towards Kingeater's Castle, and then he planned, due to lack of supplies, to go farther east in search of land. Eventually they were forced to return, but the Sigil-Ridden Navigator had misremembered their course. As their supplies dwindled, the crew resorted to cannibalism, the Navigator among them. For his mistake, he was marooned near Avid Horizon, while the rest of the crew returned to London.
Overwhelmed with guilt, the Navigator built a small rowboat and traveled to the nearby Chapel of Lights. He had a Correspondence sigil engraved on him that would make him lose his memory, so he would no longer remember what he did.
