Sure, the game focuses on the exploits of Magi, those rare people who catch a glimpse of the true nature of the universe through the study of magick. Things That Should Not Be haunt the shadows of the world, forming the basis for urban legends, creepypastas, and various other lore.
Some Magi fight against this darkness. Others seek to control it. Some seek to serve it. All risk madness and death in pursuit of their power.
The system uses an Attribute x Skill roll (I.e. you roll a number of d6 equal to your attribute and multiply by a skill rating) which gives you a pool of result points with which to determine the end result of your action.
Magick works via rituals and components. You generate result points, which are spent to purchase the strength and potency of your effects.
The basic setting is the modern world, but the corebook also includes a possible future in which Magick and Technology have been merged and humanity has taken to the stars.
Hope that helps!
