Dwala

 was the Voice of the Tempest, leader of the Air Ashari in Zephrah, prior to Keyleth.

Background
Dwala was headmaster of the Air Ashari in Zephrah prior to Vilya's attempt at the Aramenté. Dwala died of illness, either before Vilya began her Aramenté, which prompted her to begin the journey, or after Vilya had already left Zephrah.

Vilya's husband Korrin became the temporary Voice of the Tempest until their daughter Keyleth came of age and was able to complete her own Aramenté, formally succeeding Dwala as headmaster in 811 PD.
