Throne of Kil'jaeden
The mountain was so named by the warlock Gul'dan. Shortly before the opening of the Dark Portal, Gul'dan called the orc clans to the mountain to drink the blood of Mannoroth, thus enslaving them to the Burning Legion's will.
After Lord Kazzak re-opened the Dark Portal, he could be found at the Throne where he was defeated by the adventurers. Later, after the presumed defeat of Kael'thas Sunstrider, his blood elven forces were led through a portal from here to the Isle of Quel'Danas. The highest ranking members of these forces were allowed to consume demon blood, becoming the first felblood elves. Some remained at the throne and continued to consume demonic energy.
