The Desecration of Issek's Temple

Religious event

In the annals of Lankhmar's history, few events are as notorious as the Desecration of Issek's Temple. This catastrophic incident unfolded when the priests of Issek attempted to consecrate a new temple west of the revered Black Temple, the westernmost and most significant sanctuary in the city. As the rites commenced, The Gods of Lankhmar emerged from their Crypt, wreaking havoc to defend their sacred domain. The gods' wrath culminated in the obliteration of the new temple and a twelve-hour rampage, leaving hundreds dead and forever etching this day in the collective memory of Lankhmar's citizens.
