This Nerva bloke's FIGJAM incarnate. He seems to think that he's Jupiter's gift to the Island or some rubbish like that. I think his ego was actually tangible when the Legion returned from to the obelisk with the third key and the head of a dragon in tow.
Sadly, as much as I would enjoy seeing him fall flat on his face, I need him and I need the New Legion. So, when he "asked" me to guide his forces to the hidden cave, I obliged without protest.
What he'll do with me afterwards, I don't know.
