Ynys Heddwch, the Isle of Peace, has become the unwitting backdrop for a treacherous struggle between the clans of Trerone and Donethal. As the two vie for power in a series of Cattle Raids on the mainland, a band of adventurers become embroiled in this feud while visiting the Isle. Hired by a travelling minstrel, can they succeed in foiling the plot of one of the factions? Although written for the Marakush kingdom of Urtind, Ynys Heddwch is an Island setting that can be easily fitted into any fantasy campaign, rich enough to be used again and again. Intended for the new Chivalry & Sorcery: The Rebirth rules, this scenario is also useable with C&S 3rd Edition and comes with statistics for use with Harnmaster by Colombia Games Inc.
