The brotherhood of the Night's Watch has pledged to keep Westeros safe from all the horrors that live north of The Wall. Forsaking any life they might've had before joining, they are entirely committed to their vows. Within their number are the Builders. They maintain the fortifications in and around The Wall, as well as all the arms and armor used by the Night's Watch. Their forges create some of the best and hardiest gear, including the valuable crossbow. While there are the massive ballistae that act as siege weapons, as well as the Scorpions that are light enough to be taken to battle afield, they also create hand-held crossbows. They heavily train with them, becoming a fighting force of their own. Next month, Night's Watch players will be able to add the Builder Crossbowmen to their forces. Let's take a look at how they operate.
