When you run toward something everyone else is running away from, roll +nerve.
On a 10+, you get where you're going and you're useful when you arrive. Ask the GM one question about what you find; they answer honestly.
On a 7-9, you get there but the city has changed between where you started and where you've arrived. The GM describes one thing that is gone. You act anyway.
On a miss, something sees you.
