"The symbol on the two pendants is that of the Peoples’ Church of the Divine Host, a small cult that grew around the defrocked Pentecostal minister Maxwell Rayner in London during the late eighties and early nineties. I knew I recognised the name from Statement 1106922 though, currently, it just looks like a coincidence."
The name in question is Joseph Rayner, who is mentioned in MAG07: The Piper. The remains of Joseph Rayner were found next to where Wilfred, the poet who 'met the war', was found alive.
Antonio mentions an ex boyfriend named Graham. Graham from MAG03: Across the Street (the guy with the notebooks who got replaced by a monster) also mentions he's gay, so he might be the same person. Not important, just a fun fact.
Actually important here is that, according to Antonio's dreams, Gertrude died at her desk, with a look of pure horror on her face.
Gerard Keay, the burn victim with the tiny eye tattoos on his joints, is mentioned before in MAG04: Page Turner. He is the son of Mary Keay, who collects (cursed) books from the library of Jurgen Leitner. These statements take place around the same time.
The Boneturner's Tale is a book from the library of Jurgen Leitner. Leitner is previously mentioned in MAG04: Page Turner. Michael Crew (the person who returned the book) is also mentioned in that same episode, as Dominic Swain (statement giver from MAG04) says the 'Lichtenberg figure' in the book 'Ex Altiora' reminds him of his childhood friend, Michael Crew, who was struck by lightning when they were children.
Elias interrupts the recording with a complaint from Naomi Herne, the statement giver from MAG13: Alone. We also learn that the Lukas family (Naomi's family-in-law) are patrons of the Magnus Institute.
Oh and Martin is home with stomach problems, I hope he's doing okay.
Ivo Lensik, the builder, gave his own account of the events that took place at the house on Hill Top Road in MAG08: Burned Out.
Breekon & Hope Deliveries are mentioned before in MAG02: Do Not Open. They were the one who delivered the coffin and collected it again at the end of the statement.
