As far as Roland knew, the Chief Astrologer was a man of honor and responsibility. Although he had not made any particularly extraordinary contributions to the astronomical research, he had founded the Arithmetic Academy and trained many students. He also assisted with the statistical analysis. In a sense, he extended the influence of the Astrology Association and expanded this old organization into one that could rival the Society of Alchemists.
Dispersion Star had come to apologize multiple times for his negligence and failure to predict the premature appearance of the Bloody Moon. However, as Roland had been too busy with various events lately, he had dismissed him. Nobody ever anticipated that the Bloody Moon would appear so early, and Roland had never intended to rely on the Astrology Association to predict the Bloody Moon. He used their service simply because these scholars knew arithmetics.
