Cleo and Nepheron De Nile

Nepheron: More gentle and reserved than his brother. He is more observant and cautious, as evidenced by his concern that the "guest" does not faint again. He is perhaps more patient and diplomatic than Cleo, although it is possible that this is just a mask. He also has an air of ancient wisdom and experience gained from millennia of imprisonment. He appears more thoughtful and compassionate, but at the same time maintains a distance and mystery.

Cleo: Contemptuous and arrogant. He has a sense of arrogance and impatience with mere mortals. He is sarcastic, straightforward, and not inclined to hide his disdain. Despite his long imprisonment, he retains his pride and confidence in his superiority. There is a strength and authority in him that manifests itself even in short remarks.
