"There are subways here--you might see some stairs leading underground in a few places! You should get to know where at least one entrance is, and start heading for it as soon as the sun starts setting, before there's much more than just some sparks. The tunnels down there are safe from the fire, and we've made a little campsite down there, too. If you don't see any people to go with, there are glowing gold arrows on the walls of the tunnels, they all point towards there."

Someone's comfortable playing Exposition Fairy. Since he's already in infodump mode, he even thinks to throw in one more warning. "Oh, but there are some scary dogs down in the tunnels that are kind of on fire? But I guess the fire is part of them because they're magic? They can be pretty aggressive, so watch out for those."
