Overview
Nadun is a senior member of Ulzathir's council, a direct servant and child of Ozaith, and Ozaith's shard wielder when Ulzathir marches against Abraxas, the Oracles of Eternity, and the expanding Plains of Eternity. He serves Ozaith directly with Ishara, carries Ozaith's galaxy-like shard in his palm, studies maps of Myrravel and the plains, and argues for attacking north from Ulzathir.
Helena's Upbringing
When Aurelia gives birth to Helena Hyperion, Nadun expects Helena to become one of Ozaith's future wielders, with her training dependent on her awakened magic. He guards Helena in the Council Citadel while Aurelia and Ulzathir's forces march north, teaches the children of Ozaith, and introduces Alistair Toss as her teacher. Helena awakens temporal magic while under his care.
Helena has an abyss-like power beyond Nadun's understanding. He delays Ozaith's choice until Helena gains more time and control.
Myriandel Betrayal
Nadun reaches Myriandel with Ulzathir's finest mages after acclimatizing at the border of the Plains of Eternity. Myriandel is inhabited and defended when he arrives. Myrravel's story convinces Nadun that nobody can be allowed to claim the source if the danger proves true. He still continues Ulzathir's march against Abraxas and the Oracles because the plains threaten Ulzathir's border and millions of people near Khaladun.
Nadun decides to confide in Sharuzh, the second-in-command under him in the Ulzathir army. At Myriandel's lake, Sharuzh, King Ranan, and Queen Nuvyra ambush him after Nadun confirms Ozaith's absence through the shard. Nadun fights back with cosmic barriers, aether flight, and an iridescent cosmic beam. A colossal lake creature swallows him during the clash, and the fight devastates parts of Myriandel.
Sharuzh publicly blames Nadun's death on Abraxas and uses it to drive Ulzathir and Myrravel into the Eternal War against the Oracles of Eternity. After the Eternal War, Ozaith thanks Viviana and Gren for avenging Nadun.
Magic and Skills
Nadun ranks among Ulzathir's strongest mages and is the strongest Ulzathir leader in the march against Abraxas and the Oracles. Through Ozaith's shard, he can call Ozaith's attention, though the Plains of Eternity make that call unreliable. His magic includes cosmic map projection, magical sensing, aether suspension and flight, massive cosmic barriers, and destructive cosmic beams.
