"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.

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.

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.

Some are wont to lump these little, rat-like dragon-men in with goblins and orcs, bugbears and hobgoblins. They are smarter and wiser than their kin, however. The kobolds are beholden slaves to dragons and were, in ancient times, their lorekeepers and sorcerer-servants. Their clans, with names like Ironscale and Whitewing, form around a dragon master and live to serve and do its bidding.
