Starborn

The title Starborn indicates those people who can, by birthright, wield power over the Outsiders.

Description
During the psychic attack at the end of the battle of the Deeps, Lash states:

"There was a complex confluence of events, of energies, of circumstances that would have given a child born under them the potential to wield power over Outsiders."

hinting that there is something special about Dresden, and that his birth has been planned that way.

He Who Walks Behind calls Harry Dresden Child of the stars.

In Cold Days, the Erlking and Maeve refer to Dresden by the title of "Starborn".

Other Starborns
The author has stated that Elaine Mallory also has the "potential" to wield power over Outsiders:

"Harry and Elaine are just a few months apart age wise so for all intents and purposes the same age... that was one of the reasons that Justin had picked both of them to adopt, it wasn't just random kids with power."
