I was reading that abyss topic and am wandering: why are there so many insanity-induced creatures associated with far realm and none with pandemonium? Isn't pandemonium the madness plane of the great wheel?
Okay, I see how far realm is more "elemental" (but unlike elemental planes, it's on the outside) and pandemonium is mostly a home for powers, but dividing the two seems to me like a waste of a perfectly good infinity.
Any thoughts on this?
Far Realm shouldn't really be interpreted as madness, per se. It, along with all the beings that call it home, are beyond the scope of the multiverse. It is so different that space, time, and alignment have no place there. Nobody should be able to reach it at all, but there are tears in the fabric of reality. At the beginning and end of time, there is the possibility of leaving the multiverse as we know it and entering the Far Realm. Fluke events could open up a temporary path there, such as the breaking of an artifact, the death of a deity, or even throwing your portable hole into a sphere of annihilation. Because the multiverse and Far Realm are so incompatible, creatures from one have a hard time surviving in the other. Even the aberrations, which might have originated in the Far Realm, have changed to fit into the rules of the multiverse (and they still stand out among the more natural inhabitants). Considering, as I've stated earlier, the lack of direction, causality, and belief in such a place, it should be no surprise that the sods that somehow survive the horrors that flow through the squiggly solvents of the Far Realm come out a little worse for wear in the sanity department.
Pandemonium, on the other hand, is a plane of chaos with a tinge of evil. It is the place where howling winds and inexistent whispers drive a cutter to madness until the barmy loses all hope of purpose. Unlike the Far Realm, which toys with sanity because the concept does not exist there in the first place, Pandemonium is simply the embodiment of the darker side of chaos and the insanity (or lack of order and caring) that it brings about.
