Story

After Ryen suddenly becomes the King of Central at the start of the game, he and his group travel around the world of Renryuu and occasionally find hints of ancient fragments getting stolen by an unknown group. These fragments have a much greater importance than they initially realize....

Main story steps:

[Current end of the main story.]
 * After the first events at the academy, introduce yourself in the castle of Aldlyn as the new King of Central. (Quest Coronation)
 * Sir Edward will send you to the abandoned Barracks south-east of Adlyn. Defeat the ghost there, to get the angel Mira for your party. Afterwards you can talk with Sir Edward again to arrange for the repairs of the Barracks, which you can do on the country overview map.
 * General Günther in the throne room will give you the quest Bordertown, which brings you to Commander Brick in Parverhill.
 * Commander Brick will send you to Lord Herold in Witton (Quest Fragments)
 * Lord Herold will send you to Malahki in Calterburry.
 * After you talk with Malahki in the bar, you can interact with him in the church of Calterburry for the next step of the events. During the dialog with Queen Jeanne Apelia and the archbishop, the church is attacked by Lace and Emilia, who steal the fragment in the cellar of the church.
 * For the quest Armor Breaking you need to talk with Knocky in Ebron to know where to get the katryx ore to craft the Katryx Blade. The armor breaking skill of the Katryx Blade is needed to defeat Lace in the The Drunken Cave in Begus.
 * You need Chiyo in your party for the quest Fragments (3), as Frall and Varea will only appear at the broken fort in Amagal when Chiyo is in your group.
 * Varea will give you the quest Finding Lucilla. This quest will bring you into the country Dorgania. For the permission to enter Dorgania, you need to talk with the merchant Darude in front of your castle in Aldlyn.
 * When you find Lucilla in the storage in the east of Minsk Harbour, Ryen's brother Raziel will appear with his group, and reveal his plan with the fragments.
 * Ryen tries to get a fragment before Raziel can gather them all. The first goal is the fragment in a dungeon below Sunee, but they're too late.
 * Return to Varea to get the next fragment locations. However, all fragments are already gone by the time you get there. The only necessary quest step to advance the story is to talk with King Lancafew in Kagabangui.
 * The quest Final Battle will give you a fight against Raziel's group. However, the outcome of the battle is fix, and your preparation and choices only decide how much loot you get from the chests in the area.
 * At the end, Raziel gets all fragments, and it's only a matter of time before he can use them. Ryen has no other choice than to prepare himself and his country for the big battle against Raziel and the titans.
