FLASHBACK
Hye Seong entered the heavenly mansion in Dominion, the fairy kingdom. The old houses still had residences in Dominion, but younger fairies or those who had a lot of affairs in the human world didn't visit Dominion often. There were cases of young fairies who had never even known their ancestors' mansions. They had been born in the human world and never came to Dominion.
The elemental kingdom wasn't a spring garden on an eternal sunny morning as many young people imagined. It was, however, a night kingdom where the oldest magic had been used to build eternal dwellings and public buildings. The Hall of the Elements, the old Royal Palace, the Great Library, the Celestial Observatory and the Five Great Schools of Magic. And the various Advanced Schools, temples of knowledge led by great masters in their fields. One of the newest of these knowledge centers, the Master Seong Hwan Instillation School, had recently dispersed while he was away.
