Overview
Vashir is a water and sand mage from Ereshval's northern frontier and the twin brother of Drashir. During the 2107-2108 AX expansion of the Plains of Eternity toward Ereshval, he hosts Kallion and John in Qarezh, prepares an official expedition into the plains, and argues before Sultan Tharezh that Ereshval must act.
Expedition and Battle
Vashir organizes the expedition fleet with Drashir and Jin, teaches Kallion about Ereshval's defenses and water systems, and speaks for the mission at Tharezh's court. After the northern wall is overrun, he and Drashir assist the evacuation while Kallion remains in Qarezh to train Ereshval's temporal mages.
When Isandriel's expedition reaches Qarezh, Vashir grants passage through the ocean wall and knows Kallion and John from their earlier southern visit. He commands Ereshval's smaller fleet with Drashir, rights an Ereshval ship after a colossal fish attack, adapts quickly to the plains' unstable essence, and senses danger beneath the waters of Lake Eternity.
When Myrravel's army and the Ulzathir traitors engage the expedition force, Vashir and Drashir lead Ereshval's forces into the fight. They ride sand tornadoes into the enemy ranks, and Viviana later credits their arrival with saving the expedition force.
Aftermath
After Qarezh is annihilated during Thalion and Abraxas's battle, Vashir survives aboard another skyship and reunites with Drashir on the way to Rimvold. In Rimvold, the brothers discuss their responsibility to rebuild their homeland. Ereshval's survivors begin rebuilding Qarezh with aid from Nahm and Haverloch.
Much later, bronze statues outside Qarezh's Sultan's palace honor Vashir and Drashir as twin sultans and founders of Ereshval. The inscription credits them with rebuilding the capital after the cataclysmic reshaping of the land.
