Ahghairon

Ahghairon was a human mage from Northwest Faerûn and the first Open Lord of Waterdeep. He created the Lords of Waterdeep, the system by which Waterdeep has been ruled ever since, except for a six-year period immediately following his death.

Birth
Ahghairon was born on Midsummer's Night, 920 DR. Legends say that the symbol of Mystra was glowing in the sky at the time.

Rise to power
Ahghairon used his magic to win the human battle against the trolls when they were pushed down into the area now known as the Trollmoors by orc uprisings further north. At this time, Waterdeep was ruled by the Warlord Rhaulor, who wanted to use the city's power and wealth to create an empire spanning Northwest Faerûn. Ahghairon strongly disagreed with this, and when he voiced his concerns, Rhaulor attacked him. He used his magic to turn Rhaulor's sword into a snake which bit him, poisoning him. Rhaulor died and Ahghairon assumed control of Waterdeep, proclaiming himself the first Open Lord, and establishing a form of government involving Masked Lords, whose identities would remain private.

Rule
In 1007 DR, Ahghairon constructed his wizard tower, but positioned it outside the walls of Waterdeep (which have since expanded). At the same time, he imposed magical barriers on Halaster's Hold which prevented the possibility of any dangers escaping into the city.

Death
Ahghairon used potions of longevity to remain in prime physical form even though he was growing old by human standards. Eventually, his health failed in 1256 DR, and he died and was buried in his tower in Waterdeep. The tower was sealed off and protected by magic, and it is believed that his resting place has remained undisturbed ever since.
