As I understand, the unique item name generator chooses from a database; made up from: player names, realm names and other variables.
I request to include religion names within the database.
You might get something like:
The whispering codex of Sanguis Astroism
or
The shimmering blade of The Shadows
Pros: Having an item with a name related to a religion might engage and increase RP content.
Cons: None that I can see.
