The heads have been preserved, with sinuous runes carved into their leathery flesh. Their eyelids are closed, and their mouths and the muscles of their throats move as they sing. Some of the heads belonged to men of European descent, while others belonged to men and women of African descent.
The whispering song issuing from the peaceful heads has a sort of beauty, but viewing this monstrosity calls for a Sanity roll (1/1D4 Sanity points loss)
