But: If you want a guide through the swamp, you have three options: the Gnome, the hunters, of the Lizardfolk (whom you'll have to figure out how to befriend). The Lizardfolk like the Gnome. The Lizardfolk hate the hunters. The hunters hate the Lizardfolk. The villagers hate the hunters (they turned one over to the baron so he could be arrested for poaching). You don't know what the Lizardfolk think of the villagers or vice-versa.
Going through the swamp gives you the element of surprise over the villagers, if you'd like to surprise them.
Taking the roads sidesteps the politics and dangers of the swamp, but the villagers will be ready for you.
