Travel in the Known Planes of Existence

The Adventure

The Known Planes of Existence, as depicted in APPENDIX IV of the
PH, offer nearly endless possibilities for AD&D play, <>
although some of these new realms will no longer be fantasy as found in
swords & sorcery or myth but verge an that of science fiction, horror, or just
about anything else desired. How so? The known planes are a part of the
"multiverse". In the Prime Material Plane are countless suns, planets,
galaxies, universes. So too there are endless parallel worlds. What then of
the Outer Planes? Certainly, they can be differently populated if not substantially
different in form.

Spells, magic devices, artifacts, and relics are known ways to travel to the
planes. You can add machines or creatures which will also allow such
travel. As far as the universe around your campaign world goes, who is to
say that it is not possible to mount a roc and fly to the moon(s)? ar perhaps
to another planet? Again, are the stars actually suns at a distance? or are
they the tiny lights of some vast dome? The hows and wherefores are
yours to handle, but more important is what is on the other end of the

For those of you who haven't really thought abaut it, the so-called planes
are your ticket to creativity, and I mean that with a capital C! Everything
can be absolutely different,
save for those common denominators necessary to the existence of the player characters coming to the plane.
Movement and scale can be different; so can combat and morale.
Creatures can have more or different attributes.
As long as the player characters can somehow relate to it all, then it will work.
This is not to say that you are expected
to actually make each and every plane a totally new experience --
an impossibly tall order. It does mean that you can put your imagination to
work on devising a single extraordinary plane. For the rest, simply use
AD&D with minor quirks, petty differences, and so forth. If your players
wish to spend most of their time visiting other planes (and this could come
to pass after a year or more of play) then you will be hard pressed unless
you rely upon other game systems to fill the gaps. Herein I have recommended
that BOOT HILL and GAMMA WORLD be used in campaigns.



and all sorts of other
offerings which can be converted to man-for-man role-playing scenarios.
While as of this particular writing there are no commercially available
"other planes" modules, I am certain that there will be soon -- it is simply
too big an opportunity to pass up, and the need is great.

Astral and ethereal travel are not difficult, as the systems for encounters
and the chances for the hazards of the psychic wind and ether cyclone are
easily and quickly handled. Other forms of travel, the risks and hazards
thereof, you must handle as you see fit. For instance, suppose that you
decide that there is a breathable atmosphere which extends from the earth
to the moon, and that any winged steed capable of flying fast and far can
carry its rider to that orb. Furthermore, once beyond the normal limits of
earth's atmosphere, gravity and resistance are such that speed increases
dramatically, and the whole journey will take but a few days. You must
then decide what will be encountered during the course of the trip - perhaps
a few new creatures in addition to the standard ones which you
deem likely to be between earth and moon.

Then comes what conditions will be like upon Luna, and what will be
found there, why, and so on. Perhaps here is where you place the
gateways to yet other worlds. In short, you devise the whole schema just as
you did the campaign, beginning from the dungeon and environs outward
into the broad world - in this case the universe, and then the multiverse.
You need do no more than your participants desire, however. If your
players are quite satisfied with the normal campaign setting, with occasional
side trips to the Layers of the Abyss or whatever, then there is no
need to do more than make sketchy plans for the eventuality that their
interests will expand. In short, the planes are there to offer whatever is
needed in the campaign. Use them as you will.

My question is this: How much of this did you think of at the beginning? When you made OAD&D, did you think, "Oh, we could make modern-day or futuristic classes too and have a different setting!"? Did you make plans for that sort of thing or were you trying to keep it fantasy-only?

The fact is I wanted to be able to mix genres--not use the A/D&D rules to play other genres, but means of mixing genres.
Thus we had fantasy forces comprised of orcs led by an Evil cleric meeting and fighting with a Nazi anti-partizan company, and fought the battle out on a table top.
I had PCs sent to the Starship Warden to tangle with Metamorphosis Alpha characters.
No need to go on, you get the idea.
