|After completing Ophilia's Chapter 1||Flamesgrace||1,500 Leaves, Tough Nut|
Outside of the cathedral, in Flamesgrace, is a small building to the left, which has a prison cell inside. This Side Story begins by speaking with the prisoner being held inside the one cell. He claims his innocence and asks for your help in clearing his name. There are two solutions for this Side Story, both in the town of Flamesgrace. For the first one, head to the weapon shop to find a woman standing in front of it. Inquire/Scrutinize her for the information, An Eyewitness Account, then return to the man in the cell to finish.
For the other solution, you will need to head to the tavern, where you will find a Drunken Soldier at the bar. Steal/Purchase the Dungeon Key off of him (it's funny they let you buy the key), then return to the man in the cell to let him out, finishing the quest.
