IRON VOWS
In the Ironlands, a vow is sacred. When you declare your solemn promise to serve or aid someone, or to complete a personal quest, your honor is bound to that vow. Abandoning or recanting an oath is the worst sort of failure. When you swear a vow, you touch a piece of iron. It can be an iron coin, a weapon, or your armor. It’s an old tradition. Some say the iron, a piece of the primal world, serves as a conduit to the old gods—so they may better hear your promise. Vows are the core of playing Ironsworn. It is your vows that drive you. These goals create the context for your adventures and challenges. As you complete vows, you gain experience and new abilities. (Page 4 of Ironsworn Core rulebook)
