Perhaps Naagloshii have limited collective memory as a form of Intellectus, and one of the inmates originally saw the runes.

Hmm, that's interesting. However, if that were true wouldn't Shagnasty have known how to counter LTW magic? The Native American shamans had a method of dealing naagloshii so I would assume they have natural weaknesses that LTW took advantage of.

I kind of doubt that, but if say a platoon of Naagloshii attacked the island, the Warden would bind them.. If the Naggloshii who fought Harry had been in on that fight and escaped, it would remember those runes.

That may be true but why would Shagnasty return to the island that has his people imprisoned? If there was a platoon of Naggloshii that tried to break into Demonreach and Shagnasty was the only one (or one of the few) who returned he would know where the island is and that it posed a real danger to him. I really don't see Shagnasty doing research or knowing in advance that Harry was new to being the Warden, thus not having the knowledge of imprisoning him.

In tandem to this you have Crane/Madrigal setting up Splattercon as his own buffet, and opening the backdoor to Arctis Tor, the Convention and attacks would firm up the link to the Fetches abode in the Never Never in Pell’s theatre, allowing the Black Council to use it to ‘rescue’ Lea/ survey the Backdoor to Demonreach in Mab’s Ice Dungeon. We have to presume Mab was aware of an attack by the Black Council, what surprised her was the Denarian involvement.

What Backdoor to Demonreach is in Arctis Tour?

The phrase is "Someone who needs to be here." In some ways it is similar to Lea's interaction with Harry in Arctis Tor during Proven Guilty. Another way to read it is to assume the the person is healing. Much like Thomas is expected to do.

Thanks for finding the quote. I like the idea of needing healing. I wonder if being in Contemplation is another way someone could be healed from being infected by Nemesis? Or if the prisoner is infected and cannot leave because if they would, then part of Nemesis would be free to act on the world.

The unnamed prisoner says that "He belongs to be here" (paraphrasing). I wonder if Thomas will adopt this same attitude after talking with him or once he gets off the Island that he will feel that he belongs back in prison.

We know that Lea is Harry's Fairy Godmother due to a bargain that Margaret struck with her. However, the specifics are unknown to us currently. Harry benefits from Lea's protection garden in the Nevernever, when Lea continued Molly's apprenticeship, and by holding onto Margaret's red gem. Outside of these three areas, I can't think of any time when Lea did something to help Harry without Harry making a bargain of his own. So my questions are 1) What does it take to get a Fairy Godmother and can any Fae become one and 2) Margaret purposefully made a bargain with Lea, what benefits (other than those mentioned above) have or may come from said bargain?

Unless I'm missing something nowhere does it state that there needs to be two genders involved to create a baby Spirit of Intellect. So maybe instead of thinking it's Mab/Lea/Odin/Gatekeeper/whoever and someone from the opposite gender maybe it's a same-sex deal? I feel like this twist is enough to keep us guessing about who Bob's parents are while still keeping it mysterious enough.

You should find it odd that two potentially immortal beings are tied to the Oblivion War, Thomas and Lara.

How are Thomas and Lara potentially immortal?
