Faaacciinating. What part of the city is this under and are maps of the old tunnels easy to find to those who know where to look? [Since Bakura does the urbex thing, he'd know where to once he found out it was there]

And speaking of urbex, how well explored by normies are these old subway lines? [aka, how much info could he find looking em up and what kinda forum posts would there be about them?]


edit: And since Bakura has been asked to look: DOes this guy look like Proud and are there signs of food/water/toilet/living conditions or him wandering off?

Looks like surveillance is being suggested too so anything there?
