Bear with me...
I've been running a PS campaign since the Fall of '95. Over that time, there's been one sticking point that has confounded me, and has therefore caused me to do my best to steer clear of as much as possible. Despite perusing all the source material, I've never been able to identify a definitive answer. And so, I appeal to the collective knowledge here:
Are petitioners corporeal?
I've always figured that, on any given plane, the vast majority of the population are going to be petitioners. Actual planar natives are going to be substantially represented of course, contingent on the plane in question, but, petitioners would have the edge given that they're essentially immigrants coming through welcoming borders from inexhaustible sources.
So it seems to be the case that petitioners are everywhere; the 'common people' on any given plane. But, they're essentially the relocated spirits of the once alive persons from wherever it was they lived their life. So, the source material simultaneously made me think them to be either corporeal or non-corporeal. Being unable to pin down the answer to this has vexed me for years.
Sure, I've always been able to deal with it, or, more accurately, avoid it, given that it's typically easier to make use of planars but, there are cases where I've thought it would make more sense to use a petitioner.
So, taking it as granted that it's difficult to do so, given the diverse nature of all the planes, generally speaking, do you treat petitioners as corporeal or non-corporeal?
Or, have I simply missed the actual concrete answer in a text somewhere?
