Da4-will we have a name or a title?

DAO: We started as the Warden and became the Hero of Ferelden
DA2: We started as Hawke (surname) and became the Champion of Kirkwall but we already knew from the beginning that is where we were headed.
DAI: We started of as the Herald (of Andraste) and became the Inquisitor. These titles seemed interchangeable.  However, depending on your race, you were given a surname which was used on occasion, most notably when you are introduced at the Winter Palace. 

So aside from our family name in DA2 the PC has always been known by some sort of title and other people, even our companions, seem to refer to us by that. I must admit it always seemed a bit odd to me when my lover is calling me by my title instead of my own name. However, it did bring out how your own identity becomes subsumed by the legend that you become.

So I fully expect them to come up with some sort of title by which you are known in DA4. If your origins are in Tevinter then that will be fairly easy as Dorian says they love their fancy words and titles. If you are working for the Shadow Inquisition then probably you will have a code name, which could be just about anything as long as it was gender neutral.

If they allow different races then like DAI they will probably give you a surname and then people close to you may refer to you by this.
