Young Kingdoms Adventures is a supplement filled with story ideas specifically intended for Elric! or Stormbringer Fifth Edition. A listing of all of these background pages can be found at the Young Kingdoms Adventures Main Page.
The Island of the Purple Towns has been set up as a starting place for Stormbringer adventures beginning with the Elric! edition. It's very centrally located and a bastion of law, yet is big enough to provide some variety. The fourth edition book Sea Kings of the Purple Towns (CH2114) continues to be the best resource for the island; what follows just expands on that.
