"Sleep Life is supreme/supreme in its excellence" or alternatively: "Sleep Life is the ultimate"

Wizards have long supported the nation. Among them, those who were exceptionally wise and could wield numerous spells and magic were called "Sages" by the people. Among them, there was a man who became renowned as the Sage of Obsidian. The man, who was feared, shunned, and avoided, suddenly disappeared one day. All that was found was an immense amount of magical power. At some point, stories of the sage ceased to circulate, and people returned to their ordinary lives. More than ten years later. The sage, reborn in a different form and living in obscurity, sleeps quietly and alone even now.
