Notebook

 * Started the operation to liberate Eryn Village from the enhanced jaegers.
 * The teleportation stone isn't working. Maybe if we investigate the surrounding area, we can pin down what's causing this irregularity.
 * We destroyed the weird machine that was interfering with the teleportation stone. Two more remain until the barrier returns to normal.
 * Let's do what we can to keep the village safe while tracking down the other machines.
 * Shutting down the machine at the altar helped village considerably. The last device should be somewhere in the clearing on the village outskirts.
 * Defeated Gilbert and freed the village from the occupying forces.
