Sielba

Sielba or S'ielba, known as the Destroyer of Pterrans, was the 7th Champion of Rajaat and the Sorcerer-Queen of Yaramuke.

Background
Rajaat tasked Sielba to wipe out the Pterrans during the Cleansing Wars, but was later betrayed by her alongside other of his champions when Borys imprisoned Rajaat in the Hollow. Following this, during the Age of the Sorcerer-Kings, Sielba came to Yaramuke, a city built around an oasis, and became its Sorcerer-Queen and Empress, leading Yaramuke into continued prosperity as a "just tyrant". During this time, Sielba collected a vast amount of treatises on magical theory, which she used to create the black waters spell. This prosperity brought Yaramuke into competition with Urik, and its Sorcerer-King Hamanu. Despite Yaramuke's very profitable trading caravans, Hamanu controlled a valuable obsidian mine in the Smoking Crown volcano, which tipped power balance in his favour. Sielba then began to conspire with the merchant houses to wage economic warfare on Urik offering good prices to those who backed her once Urik fell, they planned to implement higher prices and embargoes on the city. However, Hamanu discovered the plots before they had begun, he amassed his armies and had them camped outside Yaramuke within a week. During Hamanu's attack on Yaramuke and Sielba's subsequent defence, the power of spells used by the sorcerers was great enough to permanently disrupt the nature of magic in areas of the city, creating Wild Magic pockets. Within a month of Hamanu learning of Sielba's plot, Yaramuke was razed to the point Sielba's former palace was a pile of rubble indistinguishable from the rest of the city. To ensure no city would grow from the ruins of Yaramuke, Hamanu cast black waters on the city's oasis, cursing those who drink from it with horrible magical sickness and ever-thirsting undeath.
