[@PhunkyPhoebe] No, most people don't have elemental abilities. Marks are ever rarer. As for abilities, think The Last Airbender: people inherit an element, but not the ability to control it. For example, imagine if your dad had air powers and your mom had water. You [i]could[i] control either air or water, but that's not guaranteed. Also, Mark's aren't inherited. So just because your parents had a Mark and found each other, doesn't mean that you will have one, too.
