Cardaen was one of the greatest elven wizards of the Age of Giants to be born outside of the Qabalrin, and was possibly one of the greatest wizards to ever live. He was raised by Emperor Cul'sir, and spent much of his life creating magic and innovating for his Giant father. When Vadallia came to break him free, he did not wish to leave, he didn't know how his people were suffering due to the magic he created. Eventually, Cardaen's eyes were opened to the suffering, but it was too late, and he held Vadallia in his arms as she died.
Cardaen swore vengeance, and when Aeren led the elves in their exodus to Xen'drik, Cardaen stayed behind. Shortly after, Emperor Cul'sir was found dead.
