Hi everyone,

I made a small change to abandoned mines:

There is now a makeshift portal appearing near every capitol that
gathers all the locations of mines to explore (if any have been made).

You can walk through that portal with your party, explore at your
heart's content and return through the same portal if you want to,
or continue forwards.

However you cannot use the portal to travel back unless you came
through it originally from the gateway.

More details inside the portal chamber(s), go and check.
