|After clearing Therion's Chapter 1||Bolderfall||2,000 Leaves|
There are two methods to completing this Side Story, although you won't have to go out of Bolderfall to do either way. The Stern Guardsman outside of the big house in the northeastern part of the main area of Bolderfall has heard word of a revolution being put together, and is wondering if there is a way to prevent this from happening. To complete the first method for this quest, you will need either Tressa or Therion. Head to Lower Bolderfall and check the contents of some of the people down to see that some of them have weapons on them. In particular, you're looking for the Rebel's Axe, Revolutionary Sword, and the Spear of Justice, so Purchase/Steal them and bring them back to the Guardsman.
For the other method, you will need either Alfyn or Cyrus. Head inside of the large house behind the Guardsman and Inquire/Scrutinize the Enlightened Aristocrat to get the Project Plans information. Bring this info back to the Guardsman to finish the quest.
