This is where you start your journey into hell itself. I would like to start by recommending you to have at least one spell caster able of casting the Blink spell in your party. You'll know what I mean when you play the scenario…
When you first arrive to McBane City the guards don't really trust you, so let them search you when they ask.
At X: 55 Y: 63 there is a blacksmith that won't be able to handle your swords too well, so be careful.
At X: 55 Y: 67 is an ordinary shop.
At X: 52 Y: 64 is a temple.
At X: 48 Y: 64 is an inn where your party can rest undisturbed.
At X: 48 Y: 65 is an inn serving all sorts of ale. If you order ale you can get useful information. Be careful, though, on sort isn't all that well…
At X: 54 Y: 73 is the gates to McBane's castle. To get past the guards you need to kill of some thieves planning to rob McBane. Read more about them in the next chapter.
