The Mage will select an appropriate object upon which to place his Mark.
This Mark will be personal in nature, and serve to identify the Mage and his possessions, chosen persons, and terrirory.
Let the mage enflame himself in his Temple and with the fire of his magic carve his glyph upon the object. If it be in public he shall do the same.
If the Mage should encounter an object which he suspects to be the property of another Mage, let him Read the object by drawing its energy out of it and "tasting" the energy to determine its owner.
The Wizard's Mark is also the forerunner of many other magical techniques.
