Nemesis is just a tool or cat's paw for what Mother Summer called simply, The Enemy...
Or 'The Enemy' is another nickname for Nemesis, like 'The Adversary'.
But I agree that there's a chance Nemesis is just a Walker, in which case the Big Bad is still the Outsiders, but we haven't seen the master. Probably Lord of Slowest Terror.
never seen it. i still stand behind Mab involved in it more so than an enemy attack. that reads more like deception than threat. if the debt is as you say, i can easily switch gears to a tricked Denarion lead/ Circle grp trying a fast strike to free Lea. they were set-up by Mab thus clearing the way for Harry.
cause seriously, you think Harry was getting in there if it wasn't wrecked?
I don't think Harry would have had to go there if it wasn't wrecked. I also don't think Mab would allow someone to destroy her home and its guards just to lure someone in. Especially since it appears that at least some of them (Namshiel and others that she said would pay) are still at large. And the fact that she seemed upset about people attacking her place. Of course, Marcone acting mad that one of his people got killed in his own plot that used his place sounds similar. Maybe both of them are nuts.
The Hellfire produced was in Harry's estimation far greater than he could produce, so either it was a whole passle of Denarians working together, or it was a user of Hellfire more powerful than a Denarian. Fallen Archangel perhaps?
It would make sense if it was the Big Guy behind everything.
Left in Arctis actor was the I egged Lea, perhaps she was the target.
It was greater than Harry could produce as a non-Denarian who hadn't taken up the coin. There's always the chance that an actual Bearer with magical ability (like Namshiel apparently had) could tap more power than Harry ever got.
My vote goes for "other" at this point, because I think there were allies involved. There is evidence of Denarian involvement, or someone or thing that could use Hell Fire, Harry confirmed that.. We know in the war against the Reds, there were Outsiders involved in the battles.. There were traders on the Senior Council, most likely working for the Circle.. There is also evidence that the attack was a tactic, and there was some kind of long game thing going on with Summer. It could be another group we haven't even heard of yet, using everyone as a gigantic cat's paw.
If you provide a who and why I'll add them to the list.
SK has Lea telling Harry specifically that Mab and Titania are powers equivalent to Archangels and lesser deities. That's pretty tough. If Mab has power roughly equivalent to Uriel (archangel) who can destroy galaxies with only a little effort, I don't think a couple of Denarians (who are not Fallen themselves) and a few B-movie 'tentacled horrors' are gonna present much of a threat.
Did she say archangels? Because no way. I think she must have meant angels. Uriel can destroy galaxies. Mab can, at most, destroy Earth, or all of reality if she neglected her duties. But I think if she did that, the Mothers would get involved.
I keep going back to this WoJ:
Nah, they wouldn't even come close. I mean... it's like comparing apples and... and hand grenades.
Just about the best they could hope to accomplish would be to force Mab to make an effort. Though when Mab came for them, it wouldn't be a kick-down-the-door-and kick-ass kind of encounter. It would be a One-two-three-four-five-Hey-weren't-there SIX-of-us-here-a-second-ago? situation.
So even with a mix of Outsiders and Denarians, there is zero chance of hurting Mab.
That's why my 'Circle Attack' theory fits. It postulates that Mab wasn't there. And if Maeve did the time slowdown, then the couple of minutes Mab and Harry chatted could have been hours. Then when Mab came back, she kicked ass, while also realizing that Maeve was infected to be working with the bad guys against her.
