"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

"Who would have thought that the goblin king would be so . . . attractive? I mean, I certainly didn't expect you to have such a lovely singing voice, at least, and . . . hold on, where are you taking my little brother? Come back here, you shiny-trousered creep!" Instinct: To find an heir

• Channel magic through dance
• Weave confusing illusions
• Dazzle into a false sense of security
• Kidnap suitable heirs

There are few single entities in the underworld more capable of destruction than a Demonic Behemoth. Behemoths are among the oldest of the damned souls that have become Demons. Like Demonic Beasts, the Behemoths forgot their intelligence, long in the past. they have survived and caused destruction and mayhem for centuries, growing to incredible size and power, such that even a Demon lord and his armies fear the rampage of Behemoth. The hate any sign of civilisation in the wasteland, and will destroy any shanty town, encampment, or keep in the Underground. Instinct: To rampage and destroy
