If you find out what came first, witches or monsters, please let me know. The research I've done so far suggests that monsters have always been around but I don't know about magic or the governing body here.

Most governments cannot survive for more than a few centuries before folding beneath their own weight. [It's a fact of history. Nothing lasts forever.] It's possible that the witches had taken power from the monsters.

I've found tensions between the two groups for as far back as I could read.
