Aways north of this town, within sight of the river,
there is a circle of standing stones. And right there is one of
those portals. This portal won't take you to a safe town or anything.
It'll take you to a nasty underground crypt full of monsters. Outsiders
call it "Rithwic Crypt"; we just call it unpleasant. But I've heard
that deep inside it you might get a mysterious key. There's outlandish
rumors about that key and just what it might be good for, but I
can't tell you anything more about it other than no one who lives
around here really knows what it's for.
