In contrast to their night elven cousins, blood elven naming conventions tend to favor the concepts of the day, the sun, and brightness/light/fire over the night, the moon, and darkness. A prefix referencing one in some way ("Brightwing," "Sunhallow," "Dawnglow," "Blazefeather," etc.) is quite common in many blood elven surnames. However, some others eschew this altogether and have fairly standard elven names that evoke no particular imagery; Lor'themar Theron himself is a prominent example of this.
Unlike the high elves, however, a number of blood elves have taken on more aggressive surnames - often incorporating the word "blood" into their identity, which had not been heard of prior to the sin'dorei coming to power. Presumably, this is to better illustrate their cultural identity and their drive for vengeance, as many blood elves would have lost family members during the Scourge massacre. Some blood elves changed their surnames as a further homage to their fallen people and loved ones, taking names such as "Bloodwatcher," "Bloodblade," and "Bloodwrath."
