Dear Marcellus,
As you have forsworn your oaths to Izdu, it makes little sense for you to manage a Temple of Izdu. I propose you rename the Temple to The Cosine Mevura Memorial Library.
It is the least you can do after sending him to his death. It is the least you can do after forcing him to participate in your blood sacrament.
Best,
Estellise Azimi
