“After subduing Thracia Castle, Seliph advanced straight for Grannvale. His army passed through the Miletos District, a independent region which had built up a sizable fortune through trade. However, all that remained was a region dying out under the empire and Lopto Sect's rule. Queen Hilda of Chronos drove numerous citizens to a hideously cruel death, while Bishop Morigan carried out merciless child hunts at Rados under orders from Archbishop Manfroy. Fortune, hope, freedom, and destiny had all been stripped from the hands of the people. The Dark Sect's sacrificial rituals, claiming one life after another, left Seliph with no other choice but to intervene. An intense battle ensued, and the Imperial Guard was driven away, and Peruluke was free once again. The liberation army received a hero's welcome from the townspeople. Their very presence began to revive the once lost hope of Miletos.”
