Is that not one of the things The Winter Lady molly now owes Ramirez??

feels like Harry Dresden is walking a similar path to Merlin

Path being the operative word here.(one I think rai can appreciate)But it's folly to limit it to simply Arthurian mythos or Merlin in said mythos. That's part and parcel why the Hades parallel scene was put in, to show a wider and wider scope of connections. GK and his appearance vs his domain being across the surface of the moon and other associations as a likely Horus put's Egyptian mythos firmly on the map too... how many is this now... Arthur, Christian, Egyptian, Greek/roman(I'd categorically have them the same).... and Norse? ^.- Mmm that's five directly connected mythos, until we see a sixth perhaps the five timelines entwined works quite well?

Unless he's already Thor, and it's part of his full cup.   

He's more the Loki to Marcones Thor... although mayhaps he's Baldor instead unless that's Thomas?

That was more about the swords and how they can be remade... Bout positive Mjolnir comes from/evolved into the sword of hope.

I don't see the link. For starters, different pantheons. Also, I'm not convinced the Mothers are utterly incapable of visiting Earth. They certainly don't do it regularly, but that could be chalked up to them not wanting to warp reality, or Mother Winter not wanting to travel without her "walking stick" and Mother Summer refraining from doing so for the sake of balance.

*snickers to self* different pantheons? My dear Sir we have in the Fae make up no less than 3 distinct pantheon's all colliding into one, lets not forget Hecate is Greek, and the two have a direct connection to the Queens based upon Hades own defense systems. Odin is Norse but is mysteriously subplanted into a largely irish mythology which Bob's fairy wars directly links to the Vanir and aesir. Separate Pantheons indeed... and besides the noticeable lack of the main greek/roman deities who later were reformed(a reforming of identity would certainly be a Godly death/twilight btw) We have Hades talk with Harry to point to a little ahh Nemfection apparent in their continued actions and we Have Thomas's soulgaze(to which I've already well connected the heirs of the sons of Ares and Aphrodite) to show the Greek pantheon is perhaps in absentee now. It suffered the same Decay as showcased in Denton's actual mind. But Thomas's soulgaze was not purely a representation of his own mind, but of his identity as a whole.
*why do they actually warp reality though? what about them disagree's with it? Look at another example, Shagnasty, whom is an angelic ghost who violates said rules by staying on earth, he warps reality only slightly because he's not quite strong enough for more, but his fundamental existence here is described through DR as wrong in the extreme, and that's before we find out we keep such creatures amongst the rejects of reality. Shagnasty is directly described as a ghost in order for the dine, an excorsim to effect him, he's also, by the very story of the skinwalkers, is describes as from a different age where he was supposed to have 'moved on' and refused. Bringing it back to the spirits who effect reality and fate whom are not supposed to. MW has no Rent, no GreenCard and has been placed on the blacklist of do not travel, for a very good reason. A cosmic level reason.

*which is NOT to say she won't one day walk the land, and for good reason. An oh my stars and garters, the day she stands up unaided by stick or escort to walk the land is a day I actually look forward to seeing in all it's terrible glory... and sadness as we watch the one who follows. ;-(

That's all an interpretation, and one that makes sense.  But it's not fact.  For the Norse pantheon, there's only one apocalypse (Ragnarok) that calls for the deaths of Odin and Loki and Thor, at least two of which are still alive regardless of the theory.

Now, if you wanted to argue that the series is in the middle of Ragnarok, and Aldar Rok has passed but Tiva Rok hasn't, it might make things more plausible.  I don't know the specifics of the series of events, but maybe it's possible.

*thinking man pose* Do we have any other thing for history and mythology..?

Yup, though I maintain that Chitzen Itza could work, with the Ambient Life of a dense Jungle replacing the need to living humans, while the same accumulation of angry warrior spirits is already present.

But.. what if it's actually the mortal choice that they're feeding on in the spell, that most delicate part of the soul only humans possess?

Yes, EK could, because he never carved off that mortal choice, same as Odin I believe.(which Woj would more or less confirm) There are 4 mortal choices floating around Fairie. And specifically, the queens and ladies are only a part of the Mothers power, we know they spun off all the lesser mantles, including then, giving the Queen the ability to make the Knight. The '3 queens' don't contribute, The two graces in opposition(tell me creator and destroyer are not archangel material, if not more) are broke down to maintain balance between the two with plenty of insulation filler in between. So Knights are indeed a created thing, from a mantle, from a grace...
Although it seems to play into the whole fallen shadow/ earthly mirror thing as part of the reason Knight's exist too.
