I am really looking forth to this.
Tom another great idea!
However one question pops up, will a realm also be able to not burn witches or perhaps get rid of these scrolss, in other words, destroy them?
I could imagine that some faiths are strongly against the use of 'evil' scrolls.
A realm can now only illigalize magic casting in general, there is not a real way to stop or prevent just the 'evil' ones, which ever that religion or philosophy might think as such.
