The Sybil vs Isaak Ferando von Kampfer

This is a "spoiler" of sorts for my Trinity Blood Fanfiction "Trinity Blood: Revelations." Appaerently the Sybil and Isaak go back and NOT in a good way.

Isaak was my favorite antagonist from the Rosenkreuz Order, one of the reasons is because he's so mysterious that you can't tell wheather he's a human or a vampire (though in the Anime they made him a Methuselah) or why he even works for Cain. I have my therories as to who and more specfifcally WHAT he is and his motives, most of which are tied with the Sybil. (How they no each other I am not saying.) Note: there is a reason why I made his characteristic jet black eyes red, its a hint as to what he is. I hope I drew him well.

Also note that like Abel, the Sybil is making a weapon out of her own blood, and note the outline of wings behind her, what in the word could she possibly be, she cannot be a Crusnik or is she...??
