The Greek afterlife isn't a hell though; it's a different paradigm entirely. Even if it was, a fallen Angel is precisely one that has separated themselves from god. Going to hell and falling may be much the same.It will have to wait for confirmation by the QM, of course.
But I remember the QM saying that it was not an absolute prohibition.
I cant really go trawling through to check right now, but I think that was mentioned at some point.
I dont think so.
The Fallen and their Coins had no trouble getting into or out of the Greek afterlife in Skin Game, and neither did Amoracchius. The Spear of Destiny, the Holy Grail, the real Shroud of Turin and a bunch of other high-end Christian artifacts were stored in Hades' vault, and are apparently stored there when shit isnt about to hit the fan in the setting, without compromise.
Michael and Amoracchius had to run down Siriothrax to kill him, presumably in his own den in the NeverNever, and Great Dragons used to be basically cosmological constants.
These are all significantly bigger players in the Dresdenverse setting than Yomi Wan individually or collectively; Hecate of the Greek Pantheon is more or less explicitly implied to be the patron and empowerment of both the Fae Courts.
Yomi Wan doesnt really get special rules by comparison IMO.
Remember that its part of the core function of a Sword to level the playing field.
Against Fallen Angels, against wannabe gods, against vampires and Titans and Great Dragons.
Yomi Wan cannot fuck with that. Any more than it can break an Exaltation.
You don't really need to troll around that much on this, a very similar discussion took place in the section of the thread I pulled that quote from. It's possible, probable even, that the special circumstances of Molly's soul world change some factors but the reason we were given was exactly what I quoted.
The absence of god is the technically that qualifies Molly's hell as a hell at all. This requires that property to be a basic one of hells as a general category. This feature is the given source of the problem.
Given that it is explicitly known to be relevant and the reason for it isn't something necessarily limited to Molly I don't think it's wise to ignore the thematics of the interaction or the broader implications of the situation.
Yami Wan might not be able to break a sword by force, but the Mortal wielders can choose to put it into situations that cause it damage.
