Singing Stone
A singing stone is a mysterious psionic device made by the Sonurians. It appears to be a simple carved stone plaque, but after prolonged exposure a person may hear “music” or have strange dreams when the stone is near.
When the monument world Sonuria was first investigated, a singing stone was found but it was recognized only as a decorative wall carving; however, Gestra Ishmethit discovered its psionic effects after spending time with it.
Travellers Anonymous were hired by Q Group to retrieve an artifact on Sonuria, and Gestra told them where to find the singing stone.
They found another singing stone in Sonurian tunnels on Hole.
