But one way or another, irregardless of my ramblings, that's your setting, what you say goes. 
Imma just wanna know provisionally. 
Can i make a divination and scrying and haruspice-oriented wizard, and if so, is it possible for a wizard of the caliber that you'd allow as a PC to use a crystal ball or a similar implement to scry and see over great, continent-sized distances or, say, project his mind into a bird in order to quickly cover large swathes of land and spy on the developments happening in faraway places?
