Cerulean Plateau

In the Aeon of the Champion story series, the Cerulean Plateau was an area of elevated ground in western Vigrith, on the remains of the Hellfire Plateau where Lucithel's citadel was located.

Lore
After the defeat of the demon prince during the Sin War, the plateau was left vacant, for the imposing citadel built above it had come crashing down spectacularly moments before. The area was long since avoided, but, after the Undertrolls found themselves excluded from the imperial revolution that swept across trollkind, they gave up hope on nomadism and made the accursed ground their home, renaming it the Cerulean Plateau after their blue skin.

The Plateau contained a font of arcane magic known as the Well of Wonders, which acted as an energy reservoir for Lucithel to power his Spire of Darkness. When the Undertrolls settled around the area and placed their village on its surface, the now serene magics of the well did them wonders, evolving the laughing stock of a race into the intelligent humanoid sarmatians ("smurfs"). The transformation also gave them an unsual aptitude for arcane magic, leading to a marked rise in the practice of the arcane in their society, and also ensured the installation of a magocracy. After the government was stabilised the sarmatians began the expansion of their territory, starting with the subjugation of their hatred troll brethren.

Destruction
During the War of the Ancients, Tiberian and his Sarmatian Resistance, in concert with the night elves, made war against King Smurf Dan'Ariz and his demonic allies, who were rapidly spawning from the dark portal created by the King and his high caste to bring Sargamon, the Dark Angel, into the physical world. Tiberian, realising that the Well of Wonders was responsible for powering the portal, struck it a deadly blow, destroying the plateau.
