Before Yi Chen arrived, only Principal Daislin mastered and excelled in the rare and difficult Star Magic, and she had ranked first in two consecutive comprehensive Prophet evaluations.
The "Rule" she formulated was simple yet effective, widely used in human villages and cities outside the organization, and it also significantly reduced the direct or indirect deaths of at least a hundred gentlemen each year due to her forecasts.
Her office, as the axis of the Omphalo-Centric-Academy (OCA), also served as the central Array that maintained the Eternal Night Barrier, privately rated as one of Zion's top ten most mysterious areas.
Rumors had it that the materials used in this office were crafted from meteorite debris that Principal Daislin brought back from the Old World, which allowed her to grow rapidly without any need for communication.
