Another observation: assuming that is Szass Tam on the standard cover, his forehead tattoos have been changed to include the Covenant of the Grave symbol. These haven’t been portrayed consistently in past illustrations.
This iconography doesn’t just suggest that the PCs might be Thayan, it...
They were very much “magic” versions of those classes, especially the ones in the Mystic UA. Consider the paladin, that was very much the sort of wizard police you might find in Thay.
It’s a background faction visible in the text on the preview photograph of Arcana Unleashed. It comes with the Arcane Undertaker origin feet.
The Cosmic Dawn is also visible, with the Transmuted Anatomy feet. The others have their names obscured, but there appears to be one for each of the...
One think that might be worth mentioning is that the Horrid Wilting spell we know is in the Arcana book was trialled in the Psion UA. But it’s a classic spell so I doubt it means much.
Not that it’s impossible, but I would consider that another example of “getting the setting wrong”. The sword and sorcery aspect is an important element, and part of that would be morally ambivalent protagonists, at least as a base line. Epic good versus evil storyline is the wrong genre.
I really don’t think season of champions feels remotely Dark Sun-ish. Season of survivors or season of desolation would be more evocative. I suspect Dark Sun will be next year, and I would rather they take their time and get it right. If you remember the Dark Sun UA we pretty much all felt that...
There was a strong case put forward for Season of Champions referring to Dragonlance, specifically a revamp of the War of the Lance adventure path. I found it convincing.
I seems to me that the issue is a narrative one: “why does this town keep attracting more and more powerful threats, up to universe shaking ones?” The best answer is, “it doesn’t”. I would be looking for a ruleset that makes the PCs less superpowered and has a low level cap.
Now I’m quite happy...
If I was writing this adventure, I would make the PCs Thayan themselves. You can do a much deeper dive into culture and society that way. And it’s supposed to tie into a book that adds a lot of player options for wizards, so it seems like there will be an expectation of a wizard-dominated party...
