The Sombre Vigil were a death cult in the Second Age that operated primarily out of Senntisten. They created a flesh giant that was fed the bodies of the dead in order to create more, acting as mobile siege engines. The flesh giant would also spread disease. They used the metal of the smith Ipcress in their work, much to the smith's anger. He attacked them using the head of a scythe but Zemouregal, who was leading the Sombre Vigil and their flesh giant to its destination, struck back, mortally wounding Ipcress and intended to feed the smith to the flesh giant as a demonstration. Harold Death appeared, taking back his scythe's head and slaying the flesh giant. It is unknown what has become of the cult since.
