Overview
Rhaeniel is a Malverand officer under Eremion. Before Eremion and Raphael's attack on Isandriel along eastern Ashenford, Eremion chooses Rhaeniel, Azarion, and Koriel as second-generation shard candidates; Rhaeniel serves with them, uses cosmic magic, and receives a shard from Eremion.
Shard and Ashenford Attack
When Eremion gives her a shard, Rhaeniel channels cosmic magic in waves of blue and white light. The shard fails to respond at first. She and Koriel then gather the army and send it to Ashenford under Eremion's command.
By the time Eremion and Raphael wait along the eastern Ashenford coast, Rhaeniel and Koriel have attuned to their shards. Azarion draws the fullest power among the three. Rhaeniel rides aboard Eremion's flagship with Azarion and Koriel during Eremion and Raphael's attack on Isandriel's expedition.
After Isandriel's fight with Eremion and Raphael on the eastern Ashenford coast resets, Eremion sends Azarion, Koriel, and Rhaeniel north to kill Isandriel and throw his Malverand heart into the ocean's deepest abyss. The mission ends when Benedict's tsunami overtakes the three mages after skyship bombardment. Azarion later survives through his implanted Malverand heart.
