"Go on, then, ye stupid puppy. Dog meat ain't to me liking, to yer own good!"
"Bruenor!" came Regis's cry from the chimney. "What are you doing?"
"I ain't running from a few skinny wolves, to be sure!"
"Bruenor. . .."
"Bah!" the dwarf snorted. He kicked at the snow, then turned around and started for the chimney, to Regis's obvious relief. The dwarf paused and looked back one more time, though, concentrating on the tall, dark shapes.
"Towers," he muttered, and shook his hairy head. He hopped into the hole, catching the remainder of the grate to break his fall.
And it hit him.
"Towers?" he said. He lifted himself up and glanced to the side at a movement, to see the glowing eyes of a wolf not ten strides away. "O, ye clever pig-face!"
Bruenor dropped from sight.
He prodded Regis to hurry along all the way down the chimney, realizing then that his precious Mithral Hall was in more danger than he had imagined. He had wondered whether Obould would try to come in through lower tunnels, or perhaps make one of his own, or whether he would try to crash through the great iron doors.
"Towers...." he muttered all the way down, for now he knew.

The next morning, a tree appeared atop the mountain called Fourthpeak, except that it wasn't really a tree, but a dwarf disguised as a tree by the druidic magic of the strange Pikel Bouldershoulder. A second tree appeared soon after, farther down the mountain slope to the west, and a third in line after that. The line of "new growth" stretched down, dwarf after dwarf, until the leading tree had a clear vantage point of the goings-on in Keeper's Dale.
When reports began filtering back to Mithral Hall about the near-readiness of the giant towers and the ghastly, ram-headed battering pole that would be suspended and swung between those obelisks, the work inside the hall moved up to a frenetic pace.
There were two balconies lining the large, oval entry hall of the western reaches of the dwarven complex. Both had crawl tunnels connecting them back to corridors deeper within the complex, and both provided fine kill areas for archers and hammer-throwers. On the westernmost side of one of these balconies, the dwarves constructed a secret chamber, large enough to hold a single dwarf. From out its top, they ran some of the same metal pipes that Nanfoodle had used to bring the hot air up on the northern ridgeline, securing them tight against the ceiling and carrying the line out to the center of the large oval chamber. A heavy rope was then threaded through the piping, secured on a crank within the small secret chamber and dangling out the other end of the pipe, nearly to the floor, some thirty to forty feet below.
All across the reaches of that chamber, the dwarves built defensive positions, low walls over which they could fend off attackers, and which afforded them a continual line of retreat back into the main corridor in the east. They coordinated those junctures in the many walls with drop-points along the ledge above. Under the watchful eye of none other than Banak Brawnanvil, the teams practiced their timing continually, for those below knew that their brethren above would likely be their only chance of getting out of the chamber alive. To further hinder their enemies, the industrious Battlehammer gang placed hundreds of caltrops just inside the great doors, some fashioned purposely and many others nothing more than sharp pieces of scrap metal - waste brought up from the forges of the Undercity.
Outside that expected battlefield, the work was no less intense. Forges glowed, great spoons in brew barrels constantly stirred, sharpening stones whirred, smithy hammers pounded away, and the many pottery wheels spun and spun and spun.
The crowning moment came late one afternoon, when a procession of dwarves carried a large, layered circular bowl into the chamber. More than fifteen feet across, the contraption was all of beaten metal, layered in fans and hooked together on a center pole that rose up just a couple of feet and ended in a sturdy eyelet. Through this, the dwarves tied off the dangling rope.
Nanfoodle nervously checked the trip-spring mechanism on the center pole several times. The tension had to be just right - not so loose that the weight of the bowl's contents could spring it, and not so tight that the drop wouldn't trigger it. He and Ivan Bouldershoulder had done the
