Saxon is unnerved by the clearly unnatural being, and Mzarem's tail is between his legs as he retreats behind his human companion. The wolf has its teeth bared at the entity but clearly doesn't have the intention of initiating hostilities.
"I think he's indicating deeper into the earth," Saxon says, "Though it's anyone's guess what the spirit's intentions are. Kyalia, you would have the magic to discern its nature wouldn't you? What hovers before us seems very much a confusing new element in our search."
Saxon sheathes his scimitar, concious of its ineffectiveness against such a creature, but maintains his guard. He wasn't sure what the ghost wanted, whether it was luring them into a trap or giving them a message, but the living dead were far from natural and he would prefer to have nothing to do with them. In hindsight Saxon realised it wouldn't have been a scent that Mzarem had picked up on, but the animal sense of the supernatural, their ability to detect that which smarter living beings could not.
