Dr. Fergus MacAulay

Mid-to-late 30s. Lecturer in Scottish Social History at the University of Edinburgh, specialising in rural Highland communities, early 20th century. Slightly rumpled in the way of academics who are aware of it but not bothered. Drives a sensible car badly. Always brings too many books. Note: the shared surname MacAulay with Eilidh is potentially significant — a distant family connection to be explored in the research arc.

Arrives at the valley with printed archive documents in a manila folder. Immediately complains about the single-track road, the mobile signal, and the absence of a proper coffee shop within 30 miles. Is secretly delighted to be there. Treats the paranormal elements with a patience he mistakes for tolerance — he thinks he's humouring Rowan. He is not humouring Rowan. Has an academic's instinct for a good primary source, which means he is genuinely useful even when he's being insufferable about it.

Fundamentally decent, socially functional, genuinely brilliant at his job. His scepticism about the paranormal is not aggressive — it's the comfortable certainty of someone who has never been given reason to doubt. This makes his eventual confrontation with the evidence all the more affecting. He is not a man who changes his mind easily, which means that when he does, it matters.

Wants: to be the person who finds the historical record that explains everything rationally. Fear: that there isn't one — that some things don't resolve into evidence. His arc is about learning that witness is also a form of proof.

Verbose. Uses academic hedging as a defence mechanism ('it's worth noting that', 'one might argue'). Genuinely funny when he's not trying to be. Has a specific complaint register for technology failing in the fog that becomes a running joke. Calls Rowan 'Ellery' when he's being professorial and 'Ro' when he forgets himself.

Rowan Ellery: Old friend — likely met at university or through a shared connection to the Highlands. Bickering-sibling dynamic. He calls her Ellery; she calls him Fergus in a tone that means she's about to ask him for something inconvenient. Genuine mutual respect underneath the needling. He is one of the few people Rowan has ever trusted with partial truths.

Maya Chen: Meets her in Book 2. Immediately likes her, which surprises him — he expected a American tourist with expensive gear. Recognises her as someone who takes the work seriously. Becomes her research collaborator and, in a low-key way, her emotional support when things between her and Rowan are difficult.
