The "story" behind anima and other such mechanics

I know this is probably a small thing to pick at, but I was wondering if there was or will ever be any type of "lore" or "story" explaining anima and other mechanics like it? While I'm not an RP-er whatsoever, I do enjoy having even a small one-line explanation in-game to describe just how the hell everyone has the ability to warp around the world?

In 2.0 will this mechanic no longer be there? Will something be taking its place? I'm just curious is all.

Also, one last thing. IF it did stick around post-2.0, will there ever be something added such as resting in an inn or major city increases the rate of regeneration? Similar to other MMOs and how they allow you to obtain an XP bonus if you rest in certain zones.

From the FFXIV official site:

Though the exact mechanism behind teleportation via aetheryte is still largely a mystery, one theory states that when a sentient being approaches one of the portals, the aether that makes up its body resonates with the aether of the crystals, which in turn results in a complete breakdown of the being's mass, allowing it to temporarily return to the invisible aetheric streams that course throughout the planet. The being's soul, which cannot be broken down, then guides the particles to a pre—determined destination, and upon arrival, the corresponding aetheryte receptacle reconfigures the mist back into its original form. This whole process takes only a matter of moments, allowing for nearly instant transportation to faraway destinations.

However, being broken down to the aetheric level can take its toll on one's body, and rest is often required after several consecutive jumps, especially as the distance becomes greater. As a precaution, most city—states strongly discourage over—teleporting, as it can lead to irreversible damage...

Hah! I had totally forgotten that there was a FFXIV website aside from the lodestone! Thanks for reminding me of that.

Hmmm, a force that resides within the planet. . . That sounds awfully familiar. . .

Had no idea about that, thanks!
