*coughs* so, Judeo-Christian wise aka people that Lu might know from his past, I have Flauros here, who was a duke of Hell. Though he didn't fall with Lucifer, but at a later date.
Then I have Beelzebub, and Samael who has also been equated with Satan by people.
And then I have Fenrir, and Andraste, both of whom will likely be annoyed by him, or something. xD
