The Realm Keeper Part 1

From publisher blurb: This is the first Extension Quest Module for the Labyrinth Adventures Gaming System... It was once a sound that meant safety for the elven city od Daevanna, but its magical tones have changed. You and your fellow adventurers begin the quest of a lifetime to make this beautiful haven safe once again from the trolls who are about to overtake the kingdom! In the distance, over the hills, you hear the magical sound of The Horn of Daevanna!
