1, Kierjadan, like Archimonde, is a subordinate of "Sageras" Sargeras, the boss of the Burning Legion. Kiel Jia Dan is a civilian and Archimonde is a military attache. They are all right-hand men of Sargeras and giants of the Burning Legion.
2. Illidan, like Malfurion, is a night elf, a good friend, and a rival in love.
Illidan took refuge in Kilgardan a long time ago. However, like the Lich King, Illidan was not very obedient, but had deep awe and fear of Kilgardan's excessive strength.
4. Arthas was originally the prince of Lordaeron Kingdom in the seven kingdoms of Terran, and later degenerated into the Lich King who commanded the natural disasters. The strength is almost the same as that of Illidan, and it is evenly matched.
cause and effect
1, Kilgardan wants to invade Azeroth, but because its power is too strong, it must use a huge energy source to open the portal to transmit to Azeroth (the stronger the intruder, the more energy the portal needs to transmit. This is why invaders are scum of war, and powerful people always show their faces at the last minute.
2. In order to successfully invade Azeroth, Kiel Jia Dan created the Lich King. Nero Zu, the Lich King, was a tool made by Kilgardan to invade Azeroth. Nero Zu, the Lich King, led to the fall of Alsace (key information: Frostmourne, tichondrius, Marganis).
3. Kilgardan gave the Lich King Neruzu strength, and this little strength from Kilgardan made the Lich King Neruzu extremely powerful. After the Scourge was founded, Ner 'Zu, the lich king who felt good about himself, began to harden his wings and refused to listen to Kilgadan.
4. Kilgardan was betrayed by the Lich King he created, but he was unable to punish him in Azeroth. He was so angry that Illidan, who was also in Azeroth, had to deal with the Lich King. Thus, there was the plot of Alsace and Illidan fighting one-on-one.
5. Arthas holds the sorrow of frost and combines with the Lich King to rule the world; Illidan acquired Gourdain's skull and became a demon with infinite magic and invincible power. It can be said that the two men at this time are almost the most powerful beings in Azeroth.
