Sygaldry, simply put, is a set of tools for channeling forces. Like sympathy made solid. For example, if you engraved one brick with the rune ule and another with the rune doch, the two runes would cause the bricks to cling to each other, as if mortared in place. But it’s not as simple as that. What really happens is the two runes tear the bricks apart with the strength of their attraction. To prevent this you have to add the rune aru to each of the bricks. Aru is the rune for clay, and it makes the two pieces of clay cling to each other, solving your problem. Except that aru and doch don’t fit together. They’re the wrong shape. To get them to fit you have to add a few linking runes, gea and teh. Then, for balance, you have to add gea and teh to the other brick, too. Then the bricks cling to each other without breaking. But only if the bricks are made out of clay. Most bricks aren’t. So, generally, it is a better idea to mix iron into the ceramic of the brick before it is fired. Of course, that means you have to use fehr instead of aru. Then you have to switch teh and gea so the ends come together properly. . . . As you can see, mortar is a simpler and more reliable route for holding bricks together.
