Here is the information in a compressed form, it leaves out some of the unusual things.
Basically the world seems to be 5 to 10% wizards with a strong bent towards a scientific focus on magic. The world is perpetually in a state of high alert due to tensions and war between all of the major countries most use wizards as their military arm due to efficiency. Terrorist groups exist usually supported by enemy governments. No monsters, everyone is as much or as little of a monster as they choose to be.
Magic usually requires massive calculation and spell formulas to use, but the Caster Assist Device allows you to get around this.
Most wizards ie use a Caster Assist Device, which basically allows evocation speed effects which is normally not even possible due to the formula for spells being overly complex. These seem to have a number of design elements and can be mass produced with quality varying by skill of a Magical Engineer allowing more efficiency or technical spell use. A few characters use gun like CAD's but a vast majority use what looks like a modern smart phone, or a bracer with a keypad.
In the country the characters are from there are 10 major clans with specialties in certain kinds of magic. They are usually the most powerful magic users think of them as the White Council with less rules...In addition to these things there are martial arts based magic styles, such as Shinobi fighting skills which focus on speed. This I think makes it easy to have some powers such as inhuman strength or inhuman speed available.
There are no enchanted items that can be used by non-magicians, or to be set up as continuous devices.
