"He's a former lighthouse keeper. The spirits found his lantern and someone managed to figure out how to repair it and bring him back. He's... I don't know him well yet. He looks like a kid, but I think he was here a long time. If you can't track him down in person, just message him on the tablet."

Since not even Rosinante is sure where he's taken up residence. He's only just met the guy himself a week or so ago, and yeah, okay, Diode comes off as a bit grating, but someone who was a keeper probably knows a hell of a lot about this place if he can be convinced to share the information.
