I realized I forgot to directly answer that other question - yes, it is a magically dominant setting, meaning every character has magical capabilities. However, that can be applied in many different ways. If someone wants to play an artificer, for example, they could use a machine as their Arcane Conduit, such as a little robot animal that follows them around or something. They can also build devices to assist them in combat, such as an enchanted crossbow or blaster pistol that fires out energy bolts or wrist-mounted web-shooter-like devices that conjure magical vines. 

Or, if someone wants to play something similar to a purely martial archetype - like warriors and fighters in TTRPGs - they can use their weapons as Arcane Conduits, and channel their abilities through that, such as a sword or axe or daggers. We'll say that during Orientation, the freshmen students go through a Sorting Ceremony where it is determined which path is best for them, including their Primary Arcane Art, Secondary Arcane Art, and Arcane Conduit. During this event, each new student takes a turn standing in front of the Crystal Mirror, and their reflection is encased in a two-tone aura that flashes through all the color combinations before stopping on the ones they are most attuned to. The inner aura is their Primary and the outer aura is their Secondary, and then their reflection is seen holding whatever their Conduit should be. If it's a warrior-like character, their reflection will probably hold a sword in a battle-ready pose. If they are a more scholarly character, perhaps their reflection will be holding a grimoire. 

After the Sorting Ceremony, the faculty writes down a list of everyone's projected starting Conduits (they can upgrade to different ones later) and has them crafted so that they will be available when classes start a few weeks after Orientation. In terms of the chronology of events, the Orientation and Sorting Ceremony are single-day affairs that take place in early August, and then the students go back home and return to the school in the first week of September when classes start, at which point they are assigned dorm rooms.
