A One-Round Dungeons & Dragons® Living Greyhawk
Iuz’s Border States Metaregional Adventure
Celebrations in the dwur mountain kingdom of Khundholm are a pleasant respite from the normal grind of adventuring life. Barandon, the Haigh Righ of the Khund (pron. “Koond”), makes only one request of his guests – that they enjoy a well laid table, comfortable quarters and the good fellowship of the Khund folk. But when a problem crops up that the Khund cannot undertake, are you willing to lend a hand to help them secure your nation’s good relations? A one-round Iuz’s Border States Metaregional adventure set in Perrenland for APLs 4-14.
Resources for this adventure include IUZ6-04 Acid Test, by Jeffery A. Dobberpuhl Esq. Thanks also to Eric Anondson.
