In the Latter Age of Earth, magi are those few born with the Mark, a quirk or atavism of their genetic code, that supports full activation of the nanotechnologic interface within their brains, allowing them to become users of the system enveloping the planet. With this linkage made and mastered, a magus may command and the world responds. They can open the vast subterranean vaults of the Ancients, contain and control willful spirits, and send clouds of doom upon their enemies.
The magi of the several collegia seek out newly emerged mages to teach them to use their gifts. Those wild talents who are not initiated into a collegium are known as sorcerers.
The place of the magi varies across the cultures of the world. Where the Instrumentality is at its strongest their practice is generally restricted, regulated, and monitored. Occasionally they are outright banned, but their abilities are simply too valuable to governments and even to the clergy for this to be a common practice.
Nevertheless, the life of a magus is often precarious. Superstitious common folk can easily turn against them, and Instrumentality zealots are often eager to find a reason to punish or imprison them. Beyond that, the very forces they wield and the knowledge they seek can easily prove dangerous to them as much as anyone else.
