Unseen University's Hex nails the math for reliable translocation -- Anon Guest
Magic has rules. This is a fact as real as the turtle that swims underneath the world. Or the four elephants on its back that support the entire disk. In order to fly, one must drop an equal weight and really know how to stick the landing. Magic can turn lead into gold, but that gold will make you sick if you hang on to it for too long. For reasons unknown, it also glows in the dark.
Hex was built to find all of the rules. It was built to twist the rules. It was built to figure out how, exactly, the rules could be bent, warped, spindled or mutilated without breaking them. It was alright saying that the Rite of Ashkente could be performed with two wooden planks and an egg, but what size egg? Did it matter if the planks were meticulously created out of a toothpick?
Fortunately for all concerned, Hex does all of this research in a purely virtual field. It works things out mathematically. Which is a lot better than the alternatives. At least, it was. Until the entire assembly of Hex went "twinkle" and vanished in a cloud of glitter.
