That's a great explanation, Conspiracy Theorist!

I agree that whoever was Warden last hadn't been there recently. Which then goes into another question. What does it take to be the Warden? Is the Sanctum Invocation enough? It is definitely the first step. Or does the Warden need to return to the island once every year or something to retain their Wardenship?

There has been a lot of speculation about the White Council and a possible connection with the Senior Council. Regardless of the truth in that debate, what is known and clear is that the Senior Council (and maybe other members as well) know about Demonreach and are afraid of its power. After all, that was the main reason why the entire Council fought against Kemmler, to prevent him from returning to the Island. So my question is since the Council knew of the Island's power and were afraid of it, why didn't they have one of their own people bind it? Why would they leave that power open for any foolish young wizard to capture it for themselves?

Honestly, I feel like Ivy was a lightweight in Battle Ground. In the Shed Aquarium battle, she fought many Denarians at once, but in Bettle Ground, she had "heavy things" floating around her. It doesn't make sense to me why if she was so skillful, she would use blunt objects as her weapon of choice. Why not a fistful of Mordite or lightning or some other more elemental or powerful weapon. While Ivy has a large magical "battery" and is very talented in some aspects, I think her human side prevents her from becoming the ultimate powerhouse she could become. Maybe as she ages, she'll learn how to use her power in other ways.

Update/edit:
On the other hand, maybe my thinking is wrong. When I was writing this, I was thinking of physical power. However, that's not what the Archive is supposed to be. While the Archive can defend itself, its main purpose and power come from knowledge. So in incidences of mass casualty (such as post Battle Ground), she can direct humanity in the most efficient ways possible and can preserve knowledge.

Do guys think he is growing due to his relationship with Harry, or does he grow as the Za Lord's Guard grows?

I like the idea of Marcone being an informant for the government; however, I just don't see it. For instance, what does Marcone get out of the deal? He already has little care for the law, so what can the government offer him to make the deal worth it? Also, if he is an informant and gets found out (which he definitely would), Lara, Mab, and the other signatories would not be happy with him. The one thing we know for sure about Marcone is that Marcone looks out for Marcone and, by extension, his people and property. Mab is much scarier than the US government and would destroy Marcone and his people if need be. Although it's a fun thought, I just don't see it coming true.

Hasn't it been stated several times by WOJ that the prisoner is not Merlin or Harry?

"Contemplation," I responded quietly. "He is to be shielded from any communication with other prisoners not enduring the same protocol."

"There was one prisoner held below in a kind of unique stasis, something that could most closely be considered sleep, though he could also awaken and perform limited communications for short periods of time."

On a recent re-read of PT, I came across these two almost through away lines, but I think they could have large story implications. I assume the original prisoner being held in status is the one from Skin Game. Assuming this is correct, then Thomas can talk with that prisoner. Will this be a good or bad thing for them both? What story things might come up because of it? Thoughts?
