Angel of the Night
"Angel of the Night" was the pet name that Goliath bestowed upon Demona in the days when they were mates, before the Wyvern Massacre of 994. It seems Goliath first called Demona this when they were "married" in 975 shortly after Prince Malcolm and Princess Elena's wedding. ("Vows") Sometimes it was shortened to "Angel" or "My Angel".  The name, of course, was derived from Goliath's perception of Demona as angelic.
