So, I have been making a list of the times during the show where there has been static in the background since I'm pretty sure it means something. I'll probably go through season two over the next few days, but here's the first season at least. I might have missed a few, so if you know of some, feel free to point them out.

Season 1:

• Mag1 (Anglerfish asking, thrice): "Can I have a cigarette?"

• Mag3 (Amy describing the thing crawling through Graham's window): And as I stared at it, it moved. It started to bend, slowly, and I realised I was looking at an arm, a long, thin arm. As it bent the joint close to where the arm ended, I think I saw another joint further down, also moving, and bending what I can only assume were elbows; it hooked the end of the limb over through the window. When I say moved, that’s not quite right. It shifted. Like when you stare at one of those old magic eye paintings and you change from seeing one picture into seeing another. I never saw anything I could actually call a hand, but still it pulled itself through his window. It took less than a second, and I didn’t get a good look at what it was, I just saw these... arms, legs? At least four of them, but there might have been more, and they kind of folded themselves through the window in a flash of mottled grey. I think that was the colour – it was mostly a silhouette, and if there was a body or head, it shifted inside faster than I could see it. The moment it was inside, the light in Graham’s flat went out, and the window slammed down behind it.

• Mag3 (Amy meeting Not-Graham): I started to make my excuses and hurry away, but he just stared at me, and smiled. “Isn’t it funny, Amy, how you can live so near and never notice. I’ll need to return the visit someday.

• Mag4 (Book title): Ex Altiora

• Mag7 (Wilfred Owen describing the War): He told me it had three faces. One to play its pipes of scrimshawed bone; one to scream its dying battle cry; and one that would not open its mouth, but when it did blood and sodden soil flowed out like a waterfall. Those arms that did not play the pipes were gripping blades and guns and spears while others raised their hands in futile supplication of mercy, and one in a crisp salute. It wore a tattered coat of wool, olive green when it was not stained black, and beneath nothing could be seen but a body, beaten, slashed and shot until nothing remained but the wounds themselves.

• Mag7 (Wilfred Owen describing the War): He told me that the War, the Piper, had come to claim him and he had begged to remain. The thing had paused its tune for but a moment. With one of its arms it reached out and handed him a pen. He said he knew it would return for him someday, but now he too would live to play its tune. The way he looked at me at that moment was the same way he'd looked at me before the shell hit, and for a moment I could have sworn I once again heard that music on the breeze.

• Mag12 (Diego Molena mumbling): The first sounded like “Asak” or “Asag”, then “Veepalach” and finally in English “The lightless flame”.

• Mag12 (Gerard Keay to the nurse): Yes, for you, better Beholding than the Lightless Flame.

• Mag12 (Jonathan talking about Diego's chanting): As far as the mystery man’s chanting goes, if it was indeed “Asag” that he was saying, then that’s quite interesting. Asag is the name of a demon in Sumerian mythology associated with disease and corruption, which doesn’t really seem to have much relevance to this statement except that it was also fabled that Asag was able to boil fish alive in their rivers. Admittedly in Sumerian myth this was because he was monstrously ugly but a curious coincidence nonetheless. “Veepalach” might also be a mishearing of the Polish word “wypalać”, according to Martin, which means to cauterize or brand. Admittedly, if Martin speaks Polish in the same way he “speaks Latin” then he might be talking nonsense again, but I’ve looked it up and it appears to check out. I can’t find anything conclusive on the phrase “the lightless flame” however; it crops up in a lot of different contexts throughout various esoteric literatures.

• Mag14 (Angela): "Some hungers are too strong to be denied."

• Mag15 (Aleana talking): Aleana agreed, but as I turned away she asked me how lost I was, in a low, grating voice.

• Mag15 (Laura being trapped): In the distance I saw the faintest point of light. It looked like a candle flame, far down the tunnel, and so weak it lit nothing but itself. It grew closer, but any hope it might have given me quickly died as it grew. It was coming towards me so slowly, and deep down I knew that it was of this place. It meant me harm. As it got closer I saw the pale hand that held it and I heard something. It was Aleana. It sounded far off and muffled, but I was sure she was calling for help. I shut my eyes for all the good it did in that place and tried desperately to will it all away.

• Mag15 (Video clip from Laura's phone): Take her not me. Take her not me. Take her not me. Take her not me. Take her not me.

• Mag17 (Book title, happens thrice throughout the statement): The Boneturner's Tale

• Mag17 (Bleeding books): Red dripped and pulsed from the cart, soaking the pages and forming a small pool around it. The books were bleeding. I laughed at that. It seemed so appropriate somehow, so utterly correct that those neighbouring books should suffer, should be contaminated by it. Just as it seemed right and proper that, when my torch found The Boneturner's Tale, it was dry, unmarked by the gory scene around it.

• Mag17 (Describing the contents of the Boneturner's Tale): It was written in prose, and certainly seemed to be a story of some kind. The part I read dealt with an unnamed man, at various points referred to as the Boneturner, the Bonesmith or just the Turner, watching an assembled group of people as they made their way into a small village. It's unclear from what I read whether he is travelling with them, or simply following them, but I remember being unsettled by the details he observed in them: the way the parson would move his hand over his mouth whenever he stared too long at the nuns or how the cook looked at the meat he prepared with the same eyes that looked at the pardoner. It was only at that point that I realised the book was describing the pilgrims from The Canterbury Tales.

• Mag17 (Excerpt from the Boneturner's Tale): I flicked ahead a few pages, and found the Bonesmith had apparently crept up to the Miller while he slept. It described him silently reaching inside him, and... it's a bit hazy. All I remember clearly is the line “and from his rib a flute to play that merry tune of marrow took”. And as for the rest, I don't recall in detail, but I know that I almost threw up, and that the Miller did not survive. This was on page sixteen, and it was a thick book.

• Mag18 (Toby Carlisle when opening the door): "What do you want?"

• Mag19 (Father Burroughs trying to pray): I felt my lips move. They made no sound that I could hear, but I felt them form every syllable. “I am not for you. I am marked.”

• Mag20 (Father Burroughs opening his bible): "Behold, thou hast driven me out this day from the face of the earth; and from thy face shall I be hid; and I shall be a fugitive and a vagabond in the earth; and it shall come to pass, that every one that findeth me shall slay me."

• Mag20 (Father Burroughs talking to Father Singh): "Spiritual pride," he said, "that has led to quite a fall."

• Mag23 (Back of coin from JW's tomb): "Für die Stille"

• Mag24 (Carved on the keyboard cover of the calliope): Be still, for there is strange music.

• Mag25 (Natalie Enis to Katherine Harper): She said that it wasn't long until they were collected by Mr Pitch.

• Mag25 (Cultists singing): The words were in some other language, but I remember they kept coming together for the words "Nee-allisand" or "allisunt", I think.

• Mag25 (Jonathan's notes post-statement): Also of note, the words "Ny Alesund". I don’t know for sure if Mr. Bilham remembered them correctly, but Tim pointed out that Ny-Ålesund is actually a small town in Norway.

• Mag25 (Jonathan's notes post-statement): That far north... during the winter... nights can last for a very long time.

• Mag26 (Sasha about Michael): Well, on that morning I paused before the window, and noticed one of the warped figures below was… off, slightly. It looked too tall, the limbs and body were very thin and almost wavy, like they didn’t have any structure or bones in them.

• Mag26 (Michael to Sasha): How would a melody describe itself when asked?

• Mag26 (Michael to Sasha): Then it said it didn't care if I or my companions lived or died, but that the flesh hive was always rash.

• Mag30 (Tom Haan to David Laylow): He said to me in perfect English: "You cannot stop slaughter by closing the door."

• Mag35 (Date stone in the room with the 14 doorways): In the centre, there was a datestone. It read: "Robert Smirke, 1835. Balance and fear".

• Mag39 (Sasha in artefact storage looking at the table and being replaced):

• Mag40 (During Not-Sasha's entire statement)
