Hi I'm new here, mostly I only registered so I can ask this one burning question... but since I think Planescape is pretty cool, someday when I have more time I may stop by again.
Anyway, my burning question is, what happens to Petitioners on the "in between planes". Meaning Ysgard, Beastlands, Bytopia, Arcadia, Acheron, Gehenna, Carceri, and Pandemonium. I know petitioners to the more "cardinal" planes eventually can become members of the Fiend/Celestial/Modron/Slaad/Rilmani races there, but I've looked long and hard and can't find corresponding races for most of these in-between planes. There are inhabitants, but none that seem to specifically come from petitioners. So what happens to petitioners on those planes... are they doomed to forever remain Petitioners forever? What forms do petitioners themselves take? (such as larvae, talking animals, whatever)
I'll answer part of the question - Petitioners who reach a certain level eventually merge with the plane becoming one with the embodiment of their life's beliefs.
