Kael, a low-rank apprentice from the outer districts, is the long-lost twin brother of Adrian, the Star King. All he ever wanted was a quiet ordinary life with his fiancée Serena. After being betrayed and humiliated, he takes the royal ring to wield sovereign power temporarily. He humiliates his foes one after another at the Dwarven Guild Selection, the Silvermoon Tower Banquet and the Kingdom Summit, and forges an alliance with Elara, the elven young lord. His true identity is finally revealed as the Archmage King of the Ars Empire, paving a new dual-path future for both the kingdom and the empire.
