Mage: The End of Days
The wizards of Ancient Egypt were the first mortals (so they claim) to utilize the power of True Names (ren in their native tongue). Legends tell that Isis learned the True Name of Ra and created Ra-Hekau, the art of controlling reality itself. These doctrines later found their way into hermetic thinking via the Cult of Mercury and formed one of the most important sympathetic connections in the hermetic paradigm. These mages were known to use their command of magic to fixate their True Name as a word of ten syllables (which did not necessarily had to form true words) which contained his mystical essence. Mistakes in pronouncing a True Name in a magical ritual can have disastrous effects. Most users of True Names use dead languages like Latin, Enochian and Egyptian to pronounce them, to not diminish their mystical significance.
