ABOUTTHIS BOOK

GURPS Banestorm is a guide tofantasy RPG adventures on the worldof Yrth, particularly the continent ofYtarria. Yrth largely resembles ourown world save that magic works thereand none of its original sapient or semi-intelligent races are human. However,an ancient dimensional vortex knownas the Banestorm has periodicallytransplanted humans and others toYtarria from Earth . . . and elsewhere.

This book is a supplement forGURPS Fourth Edition, and Yrth-based games can be run with nothingmore than this and the two volumes ofthe GURPS Basic Set. However, manygamers may wish to mine the exten-sive list of spells and rule guidelines inGURPS Magic as well as the generalcampaign concerns found in GURPSFantasy.

Most of GURPS Banestorm isintended to be read by both GMs andplayers. However, GMs may ask play-ers not to read Chapter 3, whichdetails Ytarria’s cultures; there areone or two secrets revealed there. Onthe other hand, some GMs might pre-fer to treat some of what’s said thereas old wives’ tales, uncorroboratedrumors, or complete falsehoods, justto keep players who “cheat” uncer-tain and off-balance. We definitelyencourage such stratagems. Chapter6 is mostly aimed at GMs but pro-vides suggestions and outlines ratherthan details. Players may find thissection useful when constructingtheir characters’ backgrounds.

Publication HistoryThe GURPS fantasy world of Yrth

is actually older than GURPS itself. Itfirst appeared in 1985 as the settingfor Orcslayer, by Warren Spector andSteve Jackson; this adventure focusedon the region of Caithness and workedwith the core combat system forGURPS, published the following year.

In 1986, a larger world-renderingappeared in the first edition ofGURPS Fantasy, by Steve Jackson. Ageneral guide to running fantasygames in GURPS, it also outlined Yrthas a sample setting, still focusing onCaithness. That land reappeared in1988 as the location for Aaron Allstonand J. David George’s GURPSFantasy: Harkwood, a campaign set-ting and scenario based on a feudalfief. In 1989, Alexander von Thorn’sGURPS Fantasy: Tredroy looked atthe “City of Three Laws.” Kirk Tateand Janet Naylor wrote a completelynew 1990 edition titled GURPSFantasy: The Magical World of Yrth,which plumbed the mysteries ofYtarria even further.

Yrth was the official “default” set-ting for GURPS fantasy games, butafter 1990 it was only lightly devel-oped, notably in the 1991 anthologyGURPS Fantasy Adventures, whichfeatured scenarios by Chris W.McCubbin, David Dunham, WalterMilliken, and David L. Pulver. Pyramidauthors continued to discuss Yrth;

it also received passing mentions invarious “generic” fantasy-orientedGURPS supplements over the years.

This book returns to Yrth, advanc-ing its history 15 years from its lastsubstantial depiction and bringinggame mechanics in line with GURPSFourth Edition. We’ve broadened thegeneral scope in some spots, exploredmore detail in others – and taken theopportunity to change a few things.

YtarriaThis book, like its predecessors,

focuses on the continent of Ytarria.Located in Yrth’s northern hemi-sphere, Ytarria spans roughly 3,000miles. Local climes range fromparched deserts and subtropicalforests in the south to chilly subarcticregions in the north. Humans havesettled a number of outlying islandsbut maintain contact with mainlandcultures. Some nonhuman races dwellunder the waves themselves.

Although other continents exist onYrth, ocean travel is difficult. Shipsare likely to be beset by powerful cur-rents, wild storms, monsters, andsupernatural strangeness. GMs mayview the lack of development of Ytarria’s neighbors as an invitationto design and populate these places themselves; however, GURPSBanestorm is explicitly written to pro-vide plenty of adventuring opportuni-ties as it stands.
