A One-Round Dungeons & Dragons® Living Greyhawk
Iuz’s Border States Metaregional Adventure
Draconic cults stir in the north, their reach and power becoming more powerful by the day. A concerned Gildor Arcanix, confused by recent divination answers, has once more called upon you to help find out just what these chromatic cults are up to. This time, the signs point to the dead Tangles Forest. At the same time, the Old Faith needs to learn more about how Boneheart Cranzer killed the forest. Perhaps you can kill two birds with one stone. A one-round Iuz’s Border States Metaregional adventure set in the decimated Tangles Forest in the Combination of Free Lords for APLs 4-10. This is Part Two of the Seeker of the Flesh Series and is a loose sequel to BDK4-06 Scales and Secrets, Iuz6-02 Blue Scales, Red Secrets, and BDK6-07 Love Letter. PCs that have earned the favor of Gildor Arcanix, the Old Faith Druids, the Kingdom of Johrase or the clergy of St. Cuthbert are encouraged to play this adventure. Having at least one wilderness-oriented PC at the table will prove beneficial.
Resources for this adventure include Draconomicon [Nigel Findley, et al.], Draconomicon [Collins, Williams, Wyatt], and BDK4-06 Scales and Secrets [Thowe].
