The stairs wandered down, down, down, plunging the team into darkness.
And then, oddly, light started coming from down below.
The stairs emerged into...an area of open air? Probably some kind of mystic illusion, as the more magically inclined could tell.
The area was, as Benji had suggested, a cemetary. The tombstones had the names of people of John's bloodline on them, lastly with new looking tombstones marked JOHN and MIZUKI. So, you know. That's pleasant.
One of the unmarked stones has a freshly dug grave, while six rather unsavory people sit around it, dividing up pieces of gold and arguing.
