"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

• Politely collect tribute
• Leverage townspeople through secrets
• Purify water
• Hide in darkened waters

The Stoneback Rat isn't really a rat. Rather, these armoured slugs wander the streets of forgotten cities like vermin, preying on small animals unfortunate enough to seek shelter in the ruins. Their sizzling mucus trails carry a pungent smell familiar to the seasoned explorer. The mucus can remain chemically active for hours; it's rumoured that solutions of certain plant oils can protect gear from the slime. Fire can "cure" exposed equipment, though hides and cloth may not survive the treatment. Some Stoneback Rats can spit slime, while others dash around on a multitude of legs, laying a thin, slick trail. Stoneback Rats have been known to blend into walls and pounce on prey, and even to lay slime traps on ceilings that drop at the slightest tremble underneath. The one characteristic universal to all Stoneback Rats is their puzzling propensity for hoarding. Their burrows are invariably full of some array of items, meticulously ordered by some unknown instinct. Stoneback Rats may themselves be artifacts of some ancient civilization - but of course, speculation is best reserved for academia. Instinct: To organize

• Snuffle through refuse
• Hide from large creatures
• Ambush small creatures
• Guard burrow at mortal cost
