It's a widely held truth among modern arcane scholars that Astromancy is by far the most useless of the mystical arts.
After all, why spend hours staring at the sky for a vague and cryptic prophecy that may not come true for a hundred years when a simple Augury can tell you what the traffic is going to be like downtown this afternoon with a lot less hassle?
Alexandra Constantin says the truth is written in the stars, but she's weird.
Alex is 5'11" or about 180cm tall
She's a student at the Riverton University of Thaumatury and Theology, majoring in Occult History.
Also a bit of a night owl, for obvious reasons. Okay not 'bit of', waking up at 3 in the afternoon is an early start for her.
She's a passably good student and a moderately good mage. She does well in her classes but at least so far she doesn't make many waves, outside her weird choice in discipline.
Oh and she's pretty much addicted to coffee. When she's not studying or stargazing she tends to hang out at whatever sort of all-night coffee shop or cafe she can find. Her favorite is The Coffee Cavern, since it never closes and it's right next to the school campus.
Astromancy is an ancient, compound discipline that specializes in powers associated with divination, destruction and dozens of other more specialized applications that allow it to overlap with nearly every traditional school of magic. Skilled Astromancers can peer into the future, call down heavenly energies and cloak themselves in starlight.
The trouble is that it's an unreliable discipline. Many of its spells require complex rituals to perform, or require the moon to be in a certain phase or some other specific celestial alignment for maximum effect. Even when it works, prophecies can be vague and the effects of its other spells are often inefficient. Quite simply, most people never need to conjure forth a comet to smash down upon their foes in the first place and most modern schools of magic place a great deal of emphasis on efficiency as one of the greatest virtues of sorcery.
