Excerpts from Gazetteer IV
"The heart of the Church lies within the Great Cathedral,which towers over the rooftops of Levkarest.With its last stoneset in place just twelve years ago,the Great Cathedral remainsa gleaming monument to Ezra's glory--and less overtly,to the wealth and power of her church. The Great Cathedral isa fortress of white marble and stained glass,employing its own phalanx of guards."
"The Great Cathedral looms a few blocks away. Its cavernous worship hall's ceiling is covered in marble gargoyles that represent the Legions of the Night,all shying away from the serenity of the huge icon of Ezra above the altar."
Bear in mind the church was founded by Yakov Dilisnya and it is a common misconception that Leo Dilisnya was responsible for the massacre in Castle Ravenloft. Many Barovians probably think of Ezrites as puppets of the Dilisnya family and thus Ezrites probably have a tougher time in Barovia than Morninglordians do.
Here's another excerpt from the Gazetteer for all you witch hunters.
"Their unease stems from 701 BC,when Praesidia Donella Borovsky issued an edict bluntly calling witchcraft hag magic, declaring that it invariably produced physical and spiritual corruption. The Home Faith never actively persecuted witches,but Borcans grew cold toward Hala's followers.....Praesidia Kristyn Stoyista,Borovsky's successor,rescinded the edict in 732 BC.."
May have been rescinded but whats to stop you...it is Ravenloft.
