An entire unit of men, all slain by one creature. I didn't believe it at first, your Perfection, but it appears that this is so. We have a survivor, and while at first I thought his rantings pure exaggeration... it appears to be no simple skeleton. The descriptions of the creature's abilities were eerily similar to those our brothers at Marnas Pell encountered almost a century ago: men pulled through the air to skewer themselves on the creature's blade, and attacks so quick that it was able to assault multiple opponents at once. No, your Perfection, what we have here is indeed a revenant and nothing less.
