Source of the mythic power crystals

[Daethor]

From The Midnight Isles' product description:

"...powerful crystals empowering the Worldwound’s demonic armies with mythic power."

These crystals seem to be a key component of the adventure path, and thanks to my relentless quest to read all of the answers in the "Ask James Jacobs" thread, I think I've discovered a clue to these crystal's origins.

Third: That varies. For example: when a demon lord dies, it's life essence crystalizes into something called a Nahyndrian Crystal and its corpse ends up in an Abyssal Realm called the Rift of Repose. Some deities just cease to be when they die. Others leave remains behind and their corpses rot, as seen in Abaddon. Others might drift off into strange other planes. Others might become planets. It's something that we're intentionally not going to nail down as an exact equation so that we can customize things as we wish for adventures as we go.

Nahyndrian Crystal? Where is that from (in terms of books mentioned) and what does it do? Can you use it to do anything? Like craft an awesome axe or something?

That's a sneak peek into my homebrew setting and into the upcoming "Wrath of the Righteous" Adventure Path. What do they do? You'll see for sure in about a year. :P

So, if I had to guess, the demons seem to be "mining" the Rift of Repose for these crystals somehow which are empowering them with the life force of slain demon lords. If I'm even close, then this sounds awesome! :D

Thoughts?

Hmmm, actually a bit of change to my speculation:

A closer reading of James' comment suggests that the corpse of the demon lord is in the Rift of Repose, but not necessarily the crystal composed of their life force. Still, the demons must be getting their evil, chaotic claws on those crystals and using them for no good...or law! :P

If those crystals can be used for divine ascension, then there will be some very worried conspiracy theorists out there! :)

This Adventure Path...

Spoiler:

...does not go to the Rift of Repose, but that's not the only place that portions of the dead bodies of certain demon lords end up on the Abyss...

They end up on the Cleft of Mustaches, too, I'd wager. Damn thing is like a sieve.
