A Record of Secrets

Zian Manas once met Green Dragon Cid at Nocturn Yard. Green Dragon Cid exists only to protect the relics of Knockton Yard. There is no record that they engaged in a fight, but according to the record, Green Dragon Cid explained that, If your descendant appears, then my work will be complete. According to the historian who wrote the records, Zian Manas made an agreement with Green Dragon Cid and buried a document in the plains that contained the way to defeat Cid. The location...it's here. Can this be true? The only way to verify it is to go there. Find the Secret Magic 卷轴 hidden inside the landmark of the Warrior's Bridge and take it to the Mathematician Genius south of the city plaza.
