Prior to the Shadow War and the Thayvian slave uprising, a Thayvian Evoker's Circle expedition to the elven continent came into conflict with the Silverbrook wild elven clan. To forestall further bloodshed on both sides the Queen of the clan and the Evoker's Circle commander signed a treaty in which Thay would leave wild elven lands in exchange for the Queen's daughter, Inicia Silverbrook. The commander, Tratarch, and Inicia eventually married. Much later, a disgraced Tratarch sided with and became an Eldritch Knight, despite his advancing age, and he and Inicia left Thay. Winding up back with the Silverbrook clan, Inicia became Queen of the clan when her mother stepped down to go on a personal journey. It was then that the Six Who Are One called on the elven people to unite against the Drow. Inicia was chosen to represent all of the wild elven clans at the meeting, despite still being young in elven terms. The Six Who Are One was revealed as a Rakshasa and defeated, but the elven people remained united, allying with the Eldritch Knights and Tureni army to aid Azgund during the Shadow War, with Inicia Silverbrook leading the elven forces.
Inicia and Tratarch's half-elven daughter also features prominently in the history...but that's a tale for another time.
That's all future history as far as this game is concerned. At the time of Lord Noran's War, 650, Inicia's mother would be just coming into adulthood.
