[@pandapolio]. It's a good start. I agree with Kho that Emotions (Fear) is a valid alternative to Fear (Unknown), although it depends entirely on where you want to take it and how specialised you want to be.

If you take Emotions as your Domain and Fear as your Portfolio, then you become the undisputed master of Fear. Future Portfolios which you take will pertain to other emotions (eg. Anger, Jealousy).

If you take Fear as your Domain and The Unknown as your Portfolio, then you are still capable of performing fear broadly, but you are highly specialised within that field. Future Portfolios will allow you to take other specific aspects of Fear.

Also, as you are working on your character, do consider what your character will be doing. A neat character concept is all good and well, but it means little if there is no story for that character to enact.
