Very unlikely, as it's not currently assigned to the writing team, but it's not impossible for it to see some coverage if we free up sufficient word count during development.

Some sorcery, but mostly non-sorcerous magic.

The latter.

If you wanted to do something similar at the table, an Ambition 3 Terrestial working seems like a good fit.

Thank you!

Well, we're not doing much of the actual writing. But we have brand-new locales lined up in just about every Direction, and I'm looking forward to seeing what the writing team makes of them!

It's almost all setting material, but there will be a few Quick Character write-ups, mechanical guidelines for some local magics, and maybe a few random tables.

The Five Magical Materials are more broadly efficacious for artifice and generally easier for a variety of beings to attune to than other magical materials, but they don't belong to a special metaphysical category.

We don't currently have specific plans to cover Paragon and its immediate environs in Across the Eight Directions.

As per Vance, previous editions' depictions should be a good guideline for the moment. We hope to cover demesnes and manses in more detail in an upcoming supplement.

Yes, though the presentation will always be deliberately vague so that the Storyteller can attribute those hooks to other sources if she isn't using those optional-canon Exalts in her game.

You'd have to ask the previous developers.

That's the plan; we're working on a prototype now.

Yes. 10char

Yes, it includes a handful of Terrestrial and Celestial Circle spells, along with a few new sorcerous initiations.

Information on gods in the Exigents book will be aimed primarily at designing patron gods who'll provide useful personality and design hooks for Exigent characters.

That's correct.

Every type of Exigent has "their own stuff," so I'm not sure I can provide a meaningful answer.
