Hestia Zepheros

Known as The Phoenix Exemplar, former ruler of the country of Exignis starting from the year 1 and continuing until her death.
Killed in the year 520 during the final conflict of The Serpent War. Succeeded by her younger brother, Scaldor Haphistos, who now rules over Exignis. It is presumed that Hestia's final resting place is within the volcano that Phoenix Landing was built around.
Went missing around the year 180, suspiciously near the time when Annu Adabra, an extremely powerful archlich, was captured, taken down by a strike force sent by Scaldor. Hestia's name came up again in Annu's backstory, much later, when she had struck some kind of deal with the archlich in exchange for him telling her where the World Sunder was and how to use it.
