We all arrive at the Clayr's Glacier. Roxy is feeling hesitant about going home, but she's putting on a cheerful facade. Corian is already hitting on ladies. Garnelle gives Roxy a blank stare. "You're late." Muriel hands over the scroll to Garnelle. Garnelle says Roxy is always welcome and Roxy hugs her.
Garnelle reads the scroll and crumples it. She smashes her fist into a wall. "I suppose you will be staying here for awhile." She says she will call the Nine Day Watch and takes the gold.
We head toward the glacier entrance but a giant worm sprouts up and menaces Finn. A couple Clayr come over and Finn says we had an encounter with a Free Magic creature on the way here. The Clayr ask to test his Charter Mark and call off the Charter sending. We are allowed into the cold halls of the Clayr, which feels like home to Roxy. Evie speculates that maybe the Clayr don't want the Princess to be found.
The Abhorsen quarters are really really nice and have a load of Sendings. The group takes a bit of rest and Finn heals Muriel's wounds. We have a meal and during it there's a knock on the door and Evie answers it. A young nervous Clayr courier is there and says Roxy is to meet with Garnelle in the morning to receive the message for the Prince.
Evie asks about Roxy's headspace. And also gives Muriel some pointed looks as they're talking, which Muriel ignores.
Evie does some snooping around the Abhorsen quarters. She's always looking for secrets or for any sign of being observed. She finds a small soap stone carving of a dog and pockets it. In her mind this is just to borrow, not to keep.
Meanwhile Muriel is sending back food and asking for specific orders. No one has ever seen a Sending weep in the corner before.
We need to research the stones (which Evie remembered from a book in the Library) and the artifact Evie picked up off the pirate airship. The artifact is a strange red and black pyramid that has turnable nodes. It may be from the Blood Horse tribe from the Northern region. Evie argues that Corian isn't allowed to hold the artifact.
The argument gets heated and Roxy pulls Evie aside to talk to her. Evie is mistrustful of Corian but also intrigued because she wants to know more about the Northern Isles. Eventually Evie is comforted enough and surprise-hugs Roxy.
Finn asks Corian if he and Evie have slept together and says no. But apparently he is looking for a wife. Finn is curious about the Nine Day Watch. Roxy is able to clarify some stuff and says she won't be a part of this one. No one who isn't part of the Watch is allowed to be in the room where it happens.
On the way to the Library Corian gets a lot of looks from the Clayr. We see a bunch of Librarians of all different ranks about. Roxy recognizes a slightly older Clayr Librarian, Perall. She sheepishly says hi and Perall is delighted to see Roxy again. Perall says they've missed her and she's been made Deputy Librarian. Roxy tells her the group is here to look up a few things. We are assigned bracelets.
Perall also recognizes Evie and is so happy to see her. She mentions a very dangerous mission Evie went on into the depths of the Library where some Librarians came back changed. Muriel is pretty shocked to hear this and demands to know what sort of Library this is. Perall says the book Evie is looking for is on the sixth level and "things getting pretty weird down there."
We go down to the next level which has stacks that do not seem as straight and orderly as a normal library would be. Roxy leads us through but…takes us in a circle. She admits it may have been too long. Evie instead takes us to a green door that she thinks will lead downstairs. Evie also sees a door covered by glacier ice and tries to convince us to go there instead. But she relents and just sketches the door instead; we take the green door.
The next floor is ceiling to floor hallways of stacks. There's only one path to go down and it seems to go on forever. Muriel runs her hand down the stacks and a book almost bites her! She senses the danger and snatches away her hand just in time. Muriel proclaims she will be touching no more books.
We continue down the corridor for twenty minutes with no progress. Roxy tells us the one thing we should not do is turn back or try to retrace our steps. Finn suggests maybe we visualize the door we're looking for but Roxy says that probably will not work. Evie remembers this is something she did previously and recommends we press on. Corian suddenly asks Finn about how he's faring and Finn dodges questions in the forever corridor. Finally we reach a turn that has more study carousels and more Clayr working, studying. We see a large red door and a green one. Evie recalls red doors are typically where Clayr keep non-book things and the visitor bracelets won't let us in. We choose the green door. We see a small metal mouse zipping past us. Evie grabs it and it continues to squirm, it cannot talk. Luckily Roxy knows what the mouse is – someone is in trouble. Corian volunteers to cast the Charter spell to make it reverse and lead us to the person in trouble. The mouse reverses and leads us to the next level below.
The third level has books that fly around, disappear, etc. We continue to follow the mouse to the level below.
The fourth floor is very different than the other levels. We are surrounded by ice and books are encased in the ice rather than in stacks. The mouse leads us into a room with a handful of shelves and past a Librarian trapped in ice, crouched and turned away from us. Roxy goes over to see if she can find a way into the ice room. Evie and Muriel try to warn her off because not everything is as it seems in this place. Roxy is unsure and Muriel suggests we should talk to her and yells "Oy!" at her. As we turn away it sheds its human form and bangs against the walls.
The mouse leads us into a room where a Librarian is trying to shoo away a real bore worm what seems to have bust through a wall here. Finn throws a spell of force at it but only manages to rock it back a bit. Corian Charter spells some rock shards at the worm and it flails in anger and pain. Evie casts a Diamond of Protection. Muriel conjures hamsters in a panic and tells them to swarm to the worm. Surprisingly the hamsters distract the worm and leads it out the wall that it came through.
The Librarian gets up and puts her mouse back in her waistcoat. She says the worms only occasionally come in like that. Finn asks her where the door to the Fifth level is and she gives us directions. "Whatever you do don't take the right." We see more creatures trapped behind the ice.
The fifth level has normal-looking book stacks again. Evie tries to go to the left corridor and the stacks suddenly snap shut in front of her. Evie remembers the shelves on the fifth level suddenly shift around. Roxy does a lot of help getting Muriel through the shelves. Her Librarian training prepared her well to be a mercenary. Again we see a red door and a green door. We decide to have a little rest by a little pond with fruit trees around it.
Evie sees a Librarian by the red door who is loaded down with Charter-spelled swords and other objects. Evie offers to help her but the Librarian declines. The red door is creaking closed. She peaks in while its closing but does not go in as Roxy and Muriel yell-whisper at her. As it closes shut she has a small outburst that the Librarians resting by the pond notice.
Evie is still thinking about the door encased in ice from the first level of the Library. Roxy pulls a book that describes the Clayr's Library that has info on the door. It is called "The Door That Sleeps In Darkness And Will Awake In Night." It is a bad door, apparently. Trapping things behind ice is the Clayr's normal way of dealing with unwanted Free Magic anything. After resting we go through the green door and…it looks just like the room we were in. It looks exactly the same – even the Librarians are the same. We decide to go through the shifting shelves instead.
We find the sixth level looks surprisingly like a normal library. The Clayr here seem to be renewing a lot of Charter spells. We start looking for the books Evie needs. After some searching Evie and Finn pick out the correct book. Corian finds one with hidden dirty pictures of course. Evie reads the book and gets pale. She says it's bad. And it is. And we also find a book that indicates Evie's artifact is a piece of a dead god of the Northern tribes that could not be killed except by dismantling it and spreading the pieces far apart.
A loose page falls to the floor and Evie picks it up. It's very old and it's an addendum written during King Touchstone's reign. It is a poem. It seems to be a poem about Evie, Muriel, and their lost little sister, Arielle. Muriel is very distressed and storms off. Corian goes after her while Evie, Roxy and Finn ponder the poem.
Finn points out the poem indicates Arielle is still there. Finn says he's sure they did everything they could to save her but Evie says no; they both just watched in terror.
Muriel gets back to the top floor in a hurry, kind of popping out at the entrance to the first floor. Corian is following behind her. Muriel is stubborn that she doesn't want to talk about the poem and its implications. She says she will wait for the others and "reads" a book.
Roxy notices there are an awful lot of Librarians around considering there's supposedly a large Nine Day Watch going on. Roxy mentions this to Finn. They think something is wrong and Roxy intends to ask Garnelle tomorrow. Finn suggests we ask Perall about it. They also head back to the top of the library.
