Publisher: Josh BeckelhimerThe Horn of Kardos is a campaign starter to be used with Swords and amp; Wizardry Light and then expanded for Swords and amp; Wizardry Continual Light.
Included is an adventure that can be ran using Swords and amp; Wizardry Light. There is information that you, the GM, can use to further expand the adventure into an ongoing campaign with Swords and amp; Wizardry Continual Light. It is vague enough so that each GM will have their own spin on The Horn of Kardos.
What does the return of Kardos mean in your world?
What power does The Spear of Elemental Harmony have?
What happens in your world when a rift is opened to an elemental plane?
These questions are for the GM to determine and the adventurers to discover!
