It’s in your blood, so you might as well take advantage of it. There are ten Traditions for every race, listed with that
race’s description on pages XX-XX. You may select any of the ten each time you gain a new Tradition. They give you bonuses ranging from free food to higher Hit Points and Power. Where there is a duration (in other words, if you aren’t creating
