Oberyn

Oberyn was the Fire Lord from the time that Felix was proclaimed dead, to around the year 585, when the Reformed Black Wings resurfaced at full fledged power. Originally, he was a Marshal beneath Felix, and came to ownership of the throne when it was read in Felix's will that Oberyn was to take control of the nation. Eventually, he became part of the group of benders which headed to destroy the Reformed Black Wings at the Temple of Time.
