Thorn s Mystarais a columnoutlining the community’s changesto the D&D Known World. In eachinstallment, a different take onMystara will be explored by adifferent member <strong>of</strong> the community.First outlined by David Cook in the 1981Expert Set and adventure module X1: Isle<strong>of</strong> Dread, the Known World wasexpanded by Frank Mentzer in the 1984Expert Set’s revision. Bruce Heard becamethe setting’s shepherd throughout the late80s and 90s, overseeing development(and writing a couple) <strong>of</strong> the Gazetteerline, giving readers in-depth view <strong>of</strong>countries <strong>of</strong> the Known World. Thesewere followed by the Dawn <strong>of</strong> theEmperors and Hollow World boxed sets,expanding from a single continent to theentire planet, inside and out. Bruce alsodeveloped Mystara through the Voyage <strong>of</strong>the Princess Ark and Known WorldGrimoire articles published in DragonMagazine between 1990 and 1993. Much<strong>of</strong> that work was compiled into 1993’sChampions <strong>of</strong> Mystara boxed set. Thesetting was further revised and broughtover to AD&D 2nd Edition as the“Mystara” line in 1994. Official TSRsupport in-print <strong>of</strong> the setting ended in1995.by Robert Nuttman (RobJN)MY MYSTARA— known on the web and the Piazza forumsas “Thorn’s Mystara,” is a spin on theKnown World incorporating elements fromseveral d20 products. Thorn’s Mystara maynot be for everyone. Many <strong>of</strong> the more“whimsical” features have been ignored(rather, they have yet to be addressed), andthe picture that has been developing overthe past five years has been one <strong>of</strong> a muchdarker world, haunted by the long shadowcast by Blackmoor’s ruin. Sorry, no gnomishbiplanes, and no tropical resorts on Ierendi.It began with rethinking the cause <strong>of</strong> theGreat Rain <strong>of</strong> Fire. Rather than the canonical“Blackmoor devices” exploding, myMystara’s Great Rain <strong>of</strong> Fire was started byBlackmoor devices — one device, inparticular, the Planar Disjunction Device,dubbed by the developers as Andahar’sEngine.74THRESHOLD: The Mystara Magazine Issue #1
CHERRY PICKING:Ideas too good to pass up fromlater editions (or, How I Learnedto Stop Worrying and Love thed20)I blame much <strong>of</strong> this on KeithBaker and his setting-searchwinningEberron CampaignSetting. There was much in thatsetting that evoked much <strong>of</strong> thesame “pulp and sorcery” feel I getfrom Mystara. Magewrights andartificers make perfect fits fordwarven or gnomish subclasses,with their penchant fortechnomagical tinkerings.The rules for demonic possessionmade for fantastic ideas forvillains, as well as a delightfullysinister origin for magicalweapons in a world where “Magic”is a lost art. Not only that, I wasnever satisfied with the “tradingin” <strong>of</strong> weaponry for bigger andbetter plusses. A demon housed ina blade could be bargained with toprovide whichever power mightbe necessary for a given fightagainst any manner <strong>of</strong> foes,making for some fun role-playingopportunities. Or it could beboiled down to a “battle <strong>of</strong> wills”contest resolved with a few dicerolls.The following <strong>of</strong> the Silver Flamewas also carried over. It is not“native” to Mystara, having beenbrought over by the Alphatians.Magic users took care <strong>of</strong> the rest.Reckless summoning by beast men and Afridhi overthe course <strong>of</strong> three wars and two crusades left aplague <strong>of</strong> demons infesting the planet, theirnumbers becoming more and more difficult andcostly for the Blackmoor Empire to fight <strong>of</strong>f.Blackmoor’s greatest minds at the Universitydevised the Planar Disjunction Device, which wouldsever the demons’ conduit between the Prime andtheir home plane, destroying their ability tophysically manifest. A second pulse from the Devicewas supposed to force the demons’ etherealessences back across the ethereal boundary.The secondary pulse, a planet-wide tidal wave, not<strong>of</strong> water, but <strong>of</strong> pure Radiance, did not burn thedemons away, as expected. Rather, it absorbed thedemons’ essences, as it would the soul <strong>of</strong> one failingan attempt to attain Immortality. The increase involume spilled over into the planet’s naturalmagical fields, tainting the source for “regular”(non-Radiant) magic as well. The more magic awizard used, the faster the rot and decayaccumulated, eventually driving them mad.It was in this madness that the magic users broughtdown mountains, sent seas rushing across thelands, remade continents and coastlines, andwrenched the very stars across the sky.Magic was not entirely lost, though. Clerical spellsstill work without any ill effects on its users, anddruidic magics have been found to weaken thelingering demons’ hold on the land itself. Magicfrom the Old World can be made to work, if the usercan find the rare, ancient texts. The madness caneven be staved <strong>of</strong>f, if the mage is foolish enough t<strong>of</strong>orge a pact with one <strong>of</strong> the demonic entitiessuffusing the Radiance, or with one brought overfrom the Ethereal Plane.The Radiance is not the only source <strong>of</strong> magicalpower on Mystara.
