Look at the tapestry

The tapestry is old and ornate. Within its weave it depicts a massive temple, above which hangs a cloud. Large numbers of people prostrate themselves before the temple, at the head of which stands someone dressed as a priest, holding aloft some kind of gold phallic object.

As you examine the tapestry it flutters oddly, and you push it aside to reveal another exit! The tunnel beyond is too dark to see where it leads.
