Not really.
Cases in Point:
Ymeri. Isn't
technically a Deity - albeit
has a power of lower-tier one, isn't bound by Divine constraints of "worship = change" (much).
Old Gods. Are a Deity made up of thousands of angry old men, so incoherent their rage transcends aeons, death, and Planes themselves [
].
Yet, if any are separated
somehow from green Dream, those
won't be a Deity anymore.
Green Dream. Isn't
technically a Divine Realm in it's original function - but with Old Gods growing, reached
similar function.
Imperial Deity would be us taking a basic concept of a Green Dream -
an artificial afterlife - and slapping it onto our Empire and PoB in general.
Then, withing the Dream we coalesce a Divine-like battery, narratively and metaphysically bound to the entirety of the Empire, the concept we want it to embody, and the Gods we approve of - gaining protection
and giving off constant growth for
them.
With time, the battery grows - the Empire gets better metaphysical protection from things fucking with people's souls; the Gods get more energy;
We get a larger pool of energy to draw from in case we need to do something stupidly energy-expensive (like closing the hole in Hellvens).
But, technically, that thing is
still not a God.
Rather, a Landwarden to our "Fleshforge" of a soul-realm, at best.
I think Duesal is right about the fucked-up realms.
You severely underestimate the importance of Plane of Balance for them -
Of course, we can't know
exactly how much without knowing whether the setting operates within the Crystal Spheres of dnd/Pathfinder, or
regular cosmos -
But it had been pretty established so far, that
everyone craves PoB for that exact reason.
Asmodeus was willing to halp Valyrians - just to get himself a LE Empire, who'd be sending souls
straight to Hells.
We should be
really careful about how we do things with Imperial Dream.
Best case, we just angry lots of Evil Gods barely present on PoB.
Worst case, we break flow of soulc and
everyone is our enemy.
