There is a thrift store in the northwest with a shuttered door. The exterior walls are covered in mouldy wooden shingles and the window display is aged to the point of decomposition. It is not, despite all appearances, closed. Patrons occasionally enter through the side door and leave, although they rarely find anything of interest. They also rarely find the proprietor, who never responds to the bell located on the counter. The bell does arouse his attention, however, so it would be in your best interest NOT to ring it.
Instead, simply browse for a time. If you are as well versed in the secret history as you should be by now, objects of interest and historical significance (although no real power) will catch your eye. Many of them are belongings of other phenomena, including empty jars that used to house the tobacconist’s preparations and a headset identical to the one in Viscount Bennett. Do not take any of these, or their original owners will return to collect them.
The Thrift Store is a safe location to dispose of any refuse you collect over the course of your journey, but be warned that you can only dispose of small objects, and never anything truly dangerous to anything other than kayfabe.
