They are ruled by the human looking King Loti who claims to have a device that gives them human bodies and will enslave the Earth. As King Loti's real appearance is that of a vulture-headed man, it's unsure if the device is what gives the supposedly bodiless spiritmen the beast-men bodies or if it's what makes Loti look human and will do so for the rest. Loti also has the ability to be invisible although the treatment that gives Lance Hale his superior strength also allows him to see Loti during those times. One of the spiritmen's weaknesses seems to be that by someone enacting a strong force of will through the medium of silver, their bodies can be willed out of existence. It's not easily done as it took both Myra and Professor Grey to do so against one small group of them as Hale battled them.
