Nathan Messenger is Skyla Messenger's father. He was killed by Chloe Bishop and Demetri Edinger before the events of the Celestra series.

He has had two marriages: the first to his high school sweetheart Candace Messenger and the second to Lizbeth Landon.

Nathan is a Celestra, however he is not a pure Celestra as a result of "a lot of human mixing".
