Both sidequests are starting in Acadia. But you have to do the Hunting the Hunter first, to unlock The Price of Memory.

When you enter Acadia directly turn to the right and head to the staircase. Go one level down and you'll find the Vendor Dejen. But before you can buy something from him, he'll ask you for help. This will unlock the sidequest Hunting the Hunter.
Finishing the quest will not only give you access to the next sidequest The Price of Memory, it will even unlock Dejen as a Vendor. So don't miss to talk to him again and you can buy the legendary and unique flamer Sergeant Ash with the Kneecapper effect and.....














.....the Old Reliable, a unique legendary lever-action rifle with the Two Shot weapon effect,

After you've done the Hunting the Hunter sidequest enter the room next to the staircase. In the back you'll find Cog, who is concerned about the mental state of his friend Jule and will ask you if you could speak with her. After you've argeed just follow him to meet Jule.
She will tell you about her problem and hand you out Victoria's key, indicating that the wrecked tugboat near the flames at the Southwest Harbor has something to do with her memories (just follow the mark on the map).
When you return to Acadia you'll have two speaking options. One is talking her friend Cog. Now you have to decide wether to side up with him or telling Jule what you've find out. Siding with Cog completes the quest and he will give the you the legendary Crippling Sledgehammer as a reward. But if you decide to tell Jule the truth the chance is gone and you'll miss this weapon.

When you leave the staircase on the lowest level just turn to the left. Go into the next room on the left side and you'll see a terminal, next to a door. Hacking it will open the door to the armory. Beside a lot of conventional ammo you'll also find 3 mini nukes.
