From the Back of the Book:
From the storm-lashed rocks west of fabled Evermeet to the Plains of Purple Dust, all the folk of Faerun have heard of the Harpers.
Noble fools, some call them. Crazy misguided meddlers, others say. Still others disagree. "The one true hope of the Realms," said one princess. "A shining light in the darkness of our lives," agreed a sage, "pray that it never goes out."
Just who are these mysterious, wandering folk who wear silver harp pins and walk softly in the most dangerous shadows of the Realms?
This book reveals the secrets, rules, and magic of the Harpers, including: Harper Runes, Harper Magic, The long, colorful History of the Harpers, Their evil foes, Their special Allies, The fabled high Heralds, What Harpers Do, Harper Haunts: their strongholds, and the Harpers who (literally) haunt them! Joining the Harpers, and how to become a True Harper and a Master Harper...
...And more, from favorite Harper ballads to detailed Harper NPCs. This is a sourcebook you'll turn to again and again. It lays bare the warring power groups who work behind the scenes in Faerun; no FORGOTTEN REALMS campaign is complete without it!
