"Fine," Jocasta responded testily, "but ill need some chalk."

The creature appeared to make long circuits of the city. Its path was evident from the tumbled masonry where it had squeezed past structures as well as a sheen where some kind of slime had been ground into the cavern floor. The primary path, a result of hunting or territoriality, was glossy with long use but lesser swaths of destruction demonstrated that the beast wasn't limited to its circuit. Jocasta had wondered allowed if the thing ever slept, but apparently its functions were basic enough to keep running even in what passed for rest.

"Everyone in position?" Jocasta asked as she peered over the ruin of what must have once been a smithy. This area seemed to have been industrial, though it seemed even normal dwarven homes were likely to have a small forge inside. Judging by the number of metal debris scattered around that wasn't just a religious consideration. Beren gave her a thumbs up from his position across the street, indicating the dwarves were ready. Jocasta unfastened her earrings and held them in her cupped hands. She closed her eyes and whispered a spell then breathed outwards onto the little metal dragonflies. Her breath came out as golden mist which whirled around the earrings like water flowing down a drain. Both earrings twitched and began to move, beating little wings that were suddenly more than wire and glass. The fingernail sized insects fluttered up into the air and began to buzz around Jocasta's face, darting in and out to pluck at stray hairs.

"Stop that," she whispered and then told them what she wanted. They buzzed skeptically, but then took off down the road at the speed of panicked sparrows. They spread out to either side of the street, buzzing low as though something so small could possibly be interesting to something so vast. As they approached the lifted suddenly and spread apart. Arcs of electricity jumped from one to the other as they rose until they were buzzing around the monsters enormous head. It roared as the miniature storm crackled around its head, snapping its enormous jaws this way and that. Its very size worked against it, the air it disturbed buffeting the little dragonflies out of its path as teeth the length of Jocasta's forearms clashed impotently. The beast thrash, smashing several buildings that had stood for thousands of years to piles of rubble as it twisted, spewing massive amounts of dust that light the little stabs of magic like mariners flares. It was so big that it appeared to move slowly, like a distant landslide as it turned and snapped at its tiny attackers, already fleeing back down the street whence they had come. It shook dust from every building in the city as its belly hit the ground and it began to slither after the two dragonflies, gaining speed slowly but inexorably as its vast stomach muscles contracted in kinetic zig-zags that made Jocasta queasy to watch. Less queasy if it hadn't been headed right for her. 

"If this thing kills me I swear I will haunt every last dwarf," Jocasta muttered as she gathered her arcane energies.  The beast was coming on a tremendous rate of speed now, kicking up a bow wave of broken masonry as it closed on the fleeing dragonflies. It opened its mouth and roared, blasting Jocasta with a cloacal stench she could have done without ever having experienced. The noise was literally stunning drowning out even the hammer of rock on rock for a few seconds. Beren was shouting something over the ringing in her ears but all she could do was lift her hand and stare at the chalk mark she had placed on the street. Her heart was pounding in her chest and her guts felt like acid as she spoke the arcane phrase. At first nothing seemed to happen and she panicked, thinking that she had botched the spell, then the creature began to flail erratically as it began to slide out of control. A hundred foot section of road was suddenly coated with an inch thick layer of bacon grease.  The beast was massive, but is very bulk and momentum worked against it as it suddenly couldn't get any traction. It skidded past Jocasta's hiding spot, thrashing about desperately for purchase before smashing into one of the stalagmite towers a second after a bow wave of greasy white fat. The sound was like the world ending. Masonry exploded as the ancient stairway was crushed to powder. Hundred pound pieces of stairway began to rain down, ripping free one after the other and tumbling onto the beast as the dwarven construction came down in an incredible vista of destruction. 

The beast went into spastic convulsions as it was pummeled from above by the rain of stone. Incredibly it was still alive, though when it pulled its head free of the wreck, three of its five compound eyes had been smashed to jelly. It screamed in rage and confusion as it pulled free, throwing rock in all directions. Jocasta coughed and belatedly pulled her scarf up over her face.

"Well," she gasped in a tiny voice, "I cant to all the work for you."
