"What the fuck?" The woman exhales, but quickly moves in to unlock the cuffs, before she draws her pistol and hands Luke back his baton.
"Something like that." Aulus says in amusement. "This is a physical body, but it can't leave this palace - Anai sought to that." He grunts. "She cursed me, when the city fell, that I'd be trapped here for all time, unable to take the blood of another - unable to take a body like other spirits. Unfortunately for her, there's a...loophole, you might say. I can't take the blood of another, but I can take my own blood - the body of one of my descendants." He grins, walking forward. "I didn't know it at the time, but I fathered a child during the siege, furthered my dynasty. And now you're here, and I can be free." He grins at Luke, and his eyes glow red.
