Magical Lore of Korradanth
Long ago the Tiann people learned a secret that was lost in time. They learned that Dragons and the magical essence of the world were connected.
Draconian is Magic. Magic is Draconian.
The Dragon's Tongue or Draconian, is a telepathic language that only their kind can speak and now only the oldest know it's pure form. Less mature Dragons now use a more rudimentary from of the speech, one that hardly touches upon the 'Prana of the World'.
Pure Draconian is the language of magic, derived from the Song of Creation, the mystical words that dwell within the fabric of reality itself. The same very language, that those gifted with magical talents can learn and manipulate to alter the world around them.
The cycles of magic ebb and flow with the slumbers of the Dragons. When they are dormant, the mystical world is seen as if through half closed eyes. Once powerful spells and abilities are that once flowed like a raging river are reduced to trickling streams. Thus is the way of magic. So long as Dragons are awake in the world, magic is at it's height of power.
When the Dragon's sleep the magic that is yet dormant in beings remains hidden. Perhaps their time shall come and go, without ever knowing of their gifts but once the Dragon's are awake the power radiates within them and remains so until the end of their days, even if the Dragons return to their deep dens and once more drift off to their deathly dormancy.
Human's are born with a gift within a specific realm of magic, while the Mermadon and even some Ta'kun can have a range of mystical talents. Over time, however, due to their increased life spans, magical Human's can began to learn (but not master) other orders of magic. They utilize their magical abilities by studying the ancient incantations and manuals written through the ages by other magical beings. These writings, allow magic-users to tap into their own 'magical-tongue', which is a translation of the 'Song of Creation', which when thought or spoken produces an effect that defies the natural physical order of the world set by nature.
Pure Draconian is not spoken, it is a telepathic language that generates sound and by combining the words with which a Dragon can magically alter the world around them. Only the old Dragons can do this at will, while the younger ones who no longer know the pure tongue tap into the essence of the world like any other being in order to produce and use magic. Younger Dragons, speak Draconish, which is now the common speech of their kind, a telepathic language that touches upon minds at great distances without losing it's volume. While an old Dragon can kill with a word of the pure language, they have lost that ability and thus far none have ever regained it.
Should a non-Dragon, ever learn and master Pure Draconian they would not only be able to understand the Dragons, but they would in time also be able to manipulate the Song of Creation itself, a power that would challenge the most ancient of Dragon-kind.
