We should be thankful that our foe is stupid. An army of ogres at their disposal, and the Twilight's Hammer have them working in the mines nowhere near the fight. I don't know if I chalk it up to mismanagement or an internal struggle, but either way they're in no position to defend themselves. That's where we come in. With the cult's focus divided, we have an opportunity to strike the enemy while they're vulnerable and split them further. Go to this mine and sow some chaos among their ranks.
