I was thinking that his mother would be another Fallen Angel of lesser importance than the Big D, so while not quite "Human", he only has one godly parent with the other one just being more than human. Power Wise Lucius has most of his father's powers albeit watered down, but with the more unique ability to serve as an opposing force for both "Light" and "Dark": Lucius himself prefers to be based on Satan's past as Lucifer, giving him Seraph-like abilities, however Lucius does not align himself to holy powers and the like. He is, as one of his nickname may imply, "He who casts shadows", meaning that he also has powers to counter holy and light magic (Can't make shadows without light), often to create powerful dark magic. One of Lucius's weaknesses is against more neutral forces, or at least ones outside Holy and Demonic, Good or Evil, Light or Darkness. Against those I've mentioned and he'll do pretty well, but if you pit him against say, a fire god, well Lucius doesn't have much to fight back with unless it's hellfire or holy fire.

As it stands however, Lucius doesn't really [i]know[/i] what his powers are, just that it's like his father's but also the opposite. Now if that refers to Satan or Lucifer, he'll figure out in the RP.
