A character (or a follower, or henchman) receives an "inheritance" they didn't know they had from their father or some more ancient ancestor. Note that these types of inheritances don't have to be land, wealth or possessions: sometimes certain rights were just as valuable. For instance the right to own land in certain places, the right to start a business, or be exempt from taxes, or whatever. For balance, it probably shouldn't be something too wonderful. It may even have problems attached (squatters on land, politicians who don't like people exempt from taxes, etc.).
