Everything you knowabout space is wrong.

Infinite space; stars as flam-ing spheres of super-heatedplasma; movement throughspace as a balance of scientificforces, thrust providing accel-eration and maneuverability;scientific fact backing up natu-ral phenomena; life on otherplanets built along blocks ofcarbon or silicon elements.

Forget all that. It's wrong.You can get out of the

atmosphere on the back of aroc; fly between the planetsthrough a breathable ocean ofair; sail between the crystalspheres that surround the in-habited worlds on a river ofmagical energy; encounterroving mind flayers and be-holders. The stars are livingthings in some areas, greatbowls of fire in others, and pin-points of light painted inside asphere in others.

Welcome to the SPELLJAM-MER™ universe. It is a magicaluniverse.

The SPELLJAMMER sup-plement treats the AD&D®game world, with its magic,myriad races, and dimen-sional gates as the "real"world, and builds outwardfrom there. This is a universepostulated on magical, not sci-entific, laws. There are univer-sal laws and they must beobeyed, but they are the lawsof magic, not physics—thelaws of Mordenkainen, Elmin-

ster, and Fistandantilus ratherthan Galileo, Newton, and Ein-stein. They sometimes appearstrange and random to us, whoare accustomed to the work-ings of science. But to thecharacters who have livedtheir entire lives in this envi-ronment, nothing could bemore familiar and logical.

This SPELLJAMMER sup-plement extends the AD&D®2nd Edition game into space,and does so without violatingexisting campaign material.This includes Greyhawk, theoriginal AD&D game setting;Krynn, land of the Dragon-lances; Toril, home of theForgotten Realms; and everyindividual campaign in exist-ence.

Introducing this material inyour campaign will work somechanges, certainly. It will pro-duce an entertaining and far-ranging version of the AD&Dgame which can exist along-side the standing campaign,mixing with "earthbound" ad-ventures without overshadow-ing them.

The text in this set is dividedinto two books: The Concor-dance of Arcane Space and TheLorebook of the Void. The Con-cordance (this book) should beread first. It lays out the rulesfor conducting AD&D gamesin space as well as the magicalscience behind space travel,the building and handling ofspace craft, new spells anditems of equipment, and the

"discovery" and creation ofnew worlds. The Lorebook ofthe Void discusses the races,monsters, and myriad otherunusual things that can be en-countered "out there."

Full-color heavy sheets givedeck plans and other detailson the most common space-going ships.

Finally, four maps are in-cluded in the SPELLJAMMERbox. These include a full lay-out of the Spelljammer, a huge,powerful ship of legend. It isthe Flying Dutchman of thespace lanes, the ultimate goaland dream of many a space pi-rate and adventurer. Also in-cluded is a map of a typicalspace citadel, the sort used asa port and base by many differ-ent races; a hex grid and stand-up counters for playing tac-tical space battles; and anoverview map of typical solarsystems and planetary orbitsfor diagramming new systemsand tracking the planets in acampaign.

Ships andGravity Planes

Since the gravity planeof a ship runs through itstwo horizontal axes, it ispossible to stand on the"bottom" of the boat,facing the opposite direc-tion of the rest of theship. In fact, it is feasibleto build a ship with twodecks, one topside, theother on the bottom.

The fact that this is notdone is a reflection ofboth human (and othersentient) nature andcommon sense in space.The human nature part isthe tendency to want allthings "right-side up"when working withthem, and while space-born races deny any suchsimilarity with thegroundlings they are asmuch creatures of habitas their ancestors were.

The more practical rea-son is what happenswhen two large bodiesmeet in space. The largergravity plane takes overthe smaller gravity plane,and its direction of "up"

(Continued)

Many of the details about fantasyspace can be different from cam-paign to campaign and from world toworld. All fantasy space, however,shares certain, universal basic prop-erties and capabilities. This allowsships to fly between the planets andto voyage between the crystalspheres. This chapter discusses thenature of wildspace and the manyfacets and intricacies of travel andadventure in this new arena.

Space can be divided into twotypes: wildspace and the phlogiston.

Wildspace is what comes to mindwhen we talk of "space." It is the vastemptiness that lies between the plan-ets and the stars. All space inside acrystal shell is wildspace. It is mostlyvacuum. (More correctly, most re-gions of wildspace are vacuum. Butthe cosmos is a big place and thereare exceptions to almost every rule,as shall be shown later.) Wildspace isnot truly a void, however, eventhough it is often referred to that way.The simple fact that there is "space"rules out its being a true void.

The phlogiston is a turbulent, un-stable, multicolored, fluorescent gas(or gaslike medium) which fills theregions between the crystal spheres.Very little is known for certain aboutthe phlogiston or this region.

Every planetary system known isencased within a crystal sphere. Es-sentially, the crystal sphere keepsthe wildspace in and the phlogistonout (this, of course, is a tremendoussimplification, but it is easy tograsp). Like the phlogiston, crystalspheres are a great mystery; their ori-gins and substance are unknown.

Within wildspace are the celestialbodies: planets, suns, moons, aste-roids, and a host of other items col-lectively lumped together under theheading "planetoids." Most celestialbodies have an atmosphere of somesort although it is dangerous to as-sume that this is an inviolable rule.

Celestial BodiesThe celestial body that is most fa-

miliar to typical player characters istheir home planet, be it Krynn,Oerth, Toril, or any one of hundredsof others that populate the universe.

Celestial bodies extend upward insize to that of the sun, and downwardto the size of asteroids and plane-toids. The tremendous variety that ispossible (and proven) in celestialbodies mandates that the only accu-rate definition for the term is any sig-nificantly large conglomeration ofmatter that is wheeling about in wild-space. In general, however, a celes-tial body is a planetary mass. Mosthave a regenerating atmosphere. Ce-lestial bodies can have any shape,though the most common is spheri-cal. Still, there are flat worlds, ellipti-cal worlds, cubic worlds, amorphousworlds, ring-shaped worlds, hollowworlds. Astronomers from Calim-shan have even theorized the exist-ence of a mobius world.

Celestial bodies usually, but not al-ways, have an atmosphere which isusually, but not always, breathable.The depth, or thickness, of theatmosphere is directly related to thesize of the body. The larger the body,the deeper the atmosphere. Again,these are general rules and excep-tions abound. Voyagers may encoun-ter large worlds withoutatmospheres, small worlds withthick atmospheres, and otherwisehabitable worlds with poisonous at-mospheres.

Some celestial bodies are aflame,fueled either by internal reactions orby significant access to the elemen-tal plane of fire. Such bodies arecalled suns and provide most of theheat and warmth for the celestialbodies within any particular crystalshell.
