Magic, in principle, was easy. He concentrated on what it should do, and made the signs that his intuition told him epitomised the idea. In time he learned that some designs belonged to grand concepts - a circle was "protection", a rectangle "order", but a square "containment". That knowledge was useless when a concept central to a spell refused to connect to a shape he could draw or carve.
The scribbles for "to the other side" had been clear even in a panic, taking him far further than expected.
The problem now was that he did not know what "home" was.
