The first left through the grass as you start from the harbor leads you to a locked gate. Through there you will end up in a semi-large room/basement area with a large metal grate on the floor and steam opposite some stairs leading up. Close to the left of the grate there’s a “thrum” “thrum” and if you cross the map to find the shovel you can partially dig up a silenced pistol.
You can see the silencer, but the pistol becomes visible in heightened vision. You just can’t pick it up as far as I know, unless there’s some other criteria that has to be met first. I was wondering if this was a known item and what it was for. Is there anything special about it? Is it an unlock?
The shovel is in a grassy area, not where the funeral takes place but very similar looking, over in the area where the towers are located. There are a couple of initiates there and a guard or 2 I think.
