Plan of air subjective gravity

[applecat144]

It's written that gravity in elemental plane of air works that way :

Quote:

Subjective Directional Gravity: Inhabitants of the plane determine their own “down” direction. Objects not under the motive force of others do not move.

First, does "inhabitants" refer to any living creature in this plane or rather only outsiders from the plane of air ?

Second, do people just choose their gravity as free actions no matter how ? Is it an effort and something to learn and master ?

My party will maybe soon have to travel to the plane of air and I have no idea how they'll "behave" their. I was guessing that they would just float inhert unless they got a fly speed but apparently they can "fly" by choosing where they fall so i don't know anymore.

Any living (or undead) corporeal creature. PCs too.

Stopping is a problem obviously if they don't have a fly speed, but unless they arrive in a school of air-piranhas or a thunderstorm or something, they should have some time to figure it out.
