In fear of his older sister, Embrurshaile, Iyrauroth spent centuries of his life hiding on other continents. During this time, he sired sixteen sons and daughters. Embrurshaile's death caused a magical backlash in the Weave that notified her brother of her demise. He immediately set off with his children to conquer her territory in the Galena Mountains and Thar, joining the Dark Alliance in the process and helping to lay waste to Northkeep. He later went on to destroy Tharniir, shattering the power of the Ogres of Thar.
Iyrauroth later fell into a deep slumber under the steppes of Thar that lasted for centuries.
A Cult of the Dragon cell operating north of Glister in the Galena Mountains awoke Iyrauroth by 1369 DR. They attempted to persuade him to undergo the transformation into a dracolich, and gave him offerings. Iyrauroth only found their efforts amusing.
Stirred from his rest now, Iyrauroth acted as he pleased, and took to raiding caravans crossing Thar between Glister, Melvaunt, and Phlan, including those run by the Cult. When a whole caravan to Glister disappeared and agents reported on the previously unknown black dragon's raids, the Zhentarim feared that the Cult of the Dragon was responsible. To preserve trade, they marched Zhentilar troops into Thar, to which the Cult reacted by rallying local tribes to their cause, until a war loomed.
