"Good morning," the Thing in the Well calls, "And how are we doing this morning Mrs. Westmen?" -- "Just wonderfully. How have you been keeping, Thing?" -- "Fine, fine. A little peckish, a bit in the mood for, you know, a nibble, a bite to eat. But don't worry yourself, perfectly fine." -- "It's quite alright Thing, I was just thinking I should bring by some lunch. How does a ham sound?" -- "You are too kind Mrs. Westmen, just too kind..." -- The Thing in the Well has lived in the village for longer than anyone can remember. It is traditional to fix regular meals for the Thing, and to present it with a sheep or pig on special occasions. Years ago a boy went down the well on a dare. He never returned. The subject has not been broached in the presence of the Thing. Instinct: To devour

"The Old Ones, they knew much. Not the alchemy of man nor the sorcery of warlocks and the like. No, this is the magic of gears and pulleys, the sorcery of science. Watch your every step in the tower: be wary or you may call to life the ancient defense systems. You'll know the Defenders have awoken long before you face them, that's for sure; they're louder than a stomping giant and their hulls scrape the stone walls. You'll hear them coming, I'm sure you can avoid them, go on in the tower. Me? I... I'll stay out here. Got to have a lookout post, right?"

The mating call of the otyugh is a horrible, blaring cry that sounds like a cross between an elephant dying and an over-eager vulture. The otyugh spends much of its time partly submerged in filthy water and prefers eating garbage over any other food. As a result, it often grows fat and strong on the offal of orcs, goblins and other cave-dwelling sub-humans. Get too close, however, and you’ll have one of its barbed tentacles dragging you into that soggy, razor-toothed maw. If you get away with your life, best get to a doctor, or your victory may be short lived. Instinct: To befoul

• Infect someone with filth fever
• Fling someone or something

Scarabaeus pyractomena! What a delightful creature—see how its carapace glitters in the light of our torches? Not too close now, they’re temperamental, you see. The fire in their belly isn’t just metaphorical, no. Watch as I goad the beast. Aha! A spout of flame! Unexpected, isn’t it? One of these creatures alone, if it comes up from below, can be a hellish nuisance to a farmstead or village. A whole swarm? There’s a reason they call it a conflagration of fire beetles.

One of the more potent servants of a lunar cult that shouldn't have been allowed to prosper for so long, and yet they had. A body wrought of marvelous materials clads this rail-riding automaton, with a mind made from the splintered divine essence of lunar gods giving it keen autonomous abilities. Combined together these make it a profound threat, worse, because of the flexible nature of the moonsilver that makes up its being its armaments are polymorphous: One minute it might be unleashing a hail of silvery fléchettes, next it unleashes gouts of silver-laced steam or blasts of silvery light that chill the soul, or worse even more creative things. As long as its inventions have some kind of military application at least. Its primary weakness is its limited mobility, but if its power were to be applied in a more creative sense... even that might be overcome. Instinct: To obey

• Harry foes with silver-laced artillery
• Unleash militarily-focused divine magic with vicious aplomb

Instinct: Protect the forest
