When the Dalaran was founded, these human mages just like the children
who got real guns, and didn’t understand how dangerous it is. They researched
and used the arcane magic without limits. These acts for playing magic were
quickly noted by the Burning Legion, so the demons came through the chaotic void
and arrived at Dalaran, they wanted to aggress and possess this kind of arcane
magic power owned by the human mages. The demonic forces were too powerful, so
the mages in Dalaran had to ask for help from the high elves which used to teach
them the mystery of the magic WOW
gold.
When the Master of the High Elves came to Dalaran and help them defeat
the devil, they found that the humans were going to repeat their past mistakes,
which might lead to a bigger disaster, so they warned human carefully about the
consequences of abusing magic. However, the lawmakers of the Master regimes
didn't want to give up their magical abilities, so they proposed to find a
qualified mortal, and instilled all the magic knowledge and the energy of the
WOW gold in him, who was
known as the "guardian" to protect Azeroth in the later time.
The high elves agreed with this proposal, so they established Tirisfal,
the members of parliament based on the picked high elves and the elites of the
human mages. They instill their power to the guardian and responsible for
education and to provide assistance to him. Since then, the Guardians began to
appear in Azeroth, at the same time in order to hand down the magic knowledge,
the magic government sent six higher Master to compile the previous spell of
WOW gold, and they later
became the Kirin Tor which had the greatest power in the magic government.
