If it's related to a particular deity, I'll tell you what I can find about it.
I'm gonna start with the inverted cross.
Obviously, keep in mind, this will be religious commentary. If you have negative relationships with any of these, do not read those sections. I will list the item and the religion in the title of each chapter. Thank you.
