I'd think they were fake if there hadn't been so many accounts of their attack here. Though I'm still not prepared to rule out that they are just another diversion created by the Malnosso.

If the Malnosso are telling the truth, they pose a great danger to everyone here. Their obsession with the concept of death is twisted. They've perverted concepts from Buddhist and Hindu philosophy in that they seek a death that is a final release from the torment of life. This combined with a sort of Aztec mysticism that enjoys the concept of ritual sacrifice. And they "save" anyone they can, because they think of themselves as messiahs.

They are the most dangerous sort of fanatic.
