The guys go back to the forest to check it out. They find a bunch of poisonous scorpions and sand worms, but they don't seem to be a threat to the red guards. They also find ant colonies right beneath their feet, so they've got a lot of food for thought. The purple vines are growing faster than the ants, and they're eating more and more of the undead. The red guards need to strengthen their armor first, because the undead will be able to find everything they need when they get there.
