The worship of Shekka is amongst witches, most prominently in the Old World. Her powers are to an extent limited on Titan, perhaps as a consequence of banishment to the Void with the High Lords of Evil and Chaos. However, once every thirty-seven years the rising of "Shekka's Moon" takes place. This night is a night of powerful Evil when Shekka's power on Titan is at its strongest. The Moon rises as a blood red crescent. This is the most important night for witches. It is also a night when powerful Demons can be released from Demonifuege (such as the Kurakil). This apparent subordination of Demons to Shekka adds weight to the belief that she is a Dark Lord (this term applies to both genders).
"Shekka's Moon" is also known as the "Witches Moon".
