Beastiary

Note: I have taken pictures from all over, and while you may recognize some, and know their original general mechanics, do not assume these mechanics are the same. I have changed some of their abilities to suite my story. I will make notes here as their abilities are experienced by the group.

Dream eaters 
Some mix of intelligent insect. Extra dimensional/terrestrial. Telepathic. Cause of sleep. It is linked to the human DNA and wave length. The humans only have to be in close proximity to a sleeper to be linked, and hence sleep as well. Can exist in space. Killable if reached.

Insectoid. Size of a dog, though functions like dragonflies and praying mantises. The stinger on it's tail has to functions. To suck the life energy out of a victim, like a spider, and to implant eggs.

Shogoths 
Maddening amorphous blobs from under the arctic. There are stories of such, but as it is supposed to be fiction, I don't know how much to believe.
