Tyranny of Dragons
The Harpers are a semi-secret organization dedicated to promoting good, preserving history (including art and music of old) and maintaining a balance between civilization and nature by keeping kingdoms small and the destruction of animal and plant life to a minimum.
Those Who Harp were led by a council of High Harpers, who were responsible for most of the group's long-term plans and goals. High Harpers were elected through the means of secret ballots among the other High Harpers, with the criteria being long time service and extreme discretion in the implementation of their plans.
The Harpers have disbanded several times, but after each time they eventually reformed one way or another.
