I saw my fair share of the dead during the fighting, but I imagine most of the bodies will have been moved by now. Your best bet is to ask the Legionary if you can access them.

But yeah -- influential people disappearing and being replaced by others imitating their appearance was something a certain group in my world used, so I wouldn't rule it out here, too. Though if that was the case, wouldn't it be counterproductive for Zenith to then assassinate him...?
