Festival Stone of Evensong
From Drunkapedia
"The Stone of Evensong guards the shore of the river we call Prosper, near Holtburg at 36.5E, 42.1N. This stone seems to lie near the end of the ruins of a temple complex built over the river. The presence of a monolithic head statue suggests that this was not a temple in the favor of the High Empyrean -- but that is a lesson for another day." -- Alatar Locke, The Festival Stones of the Empyreans
