Within a day of the previous attack, two wraiths of snow struck from the west. The enormous, snowy humanoids rushed towards the curtain wall, and the military, always ready, prepared for the attack. While they were preoccupied, one of the wraiths moved around the base of the stairwell, killing a passing merchant who was participating in the construction of the temple. The two demons were quickly overcome, however - but it seems that when one threat is neutralized in hell, another appears to replace it.
For no sooner than the wraiths been destroyed, five of their snowy kin appeared from the north. The fiends took flight, shrieking out of a purple vortex towards the line of dwarves hauling the body and equipment of Kol Claspedrelief back to the fortress. The military, fresh from one battle, moves across the barren landscape to eagerly join another. The civilians scatter, and four of the demons choose the closer targets presented by the fortress' warriors, and are quickly slain. One ranges far, however, and kills two dwarves before it can be caught and destroyed.
With the military away, chasing after the wraith of snow, the forces of hell sense a weakness. A mite brute strikes from the west, and manages another kill before it can be neutralized.
When the adamantine spire was breached, the demonic army struck in force, but it was turned away like a copper arrow striking a steel shield. Now, perhaps, they have found the weakness of the dwarves, and strike blow upon blow, content to win the battle against the dwarves through attrition.
As the dwarves retreat to the relative safety of the curtain wall, the prince surveys the landscape. The plain, greyish landscape is littered with various pieces of equipment, and the maimed and severed body parts of those dwarves who dropped them in an attempt to escape their final fate. Commander Libash and a handful of military dwarves are in traction in the dome far above, and the steel foundations of the temple, rising amidst a swirling haze of purple light to the south-east, remain woefully unfinished. Perhaps it will always remain so - a final testament to the will of the dwarves, that after a hundred years of grinding fate, it was only the forces of hell, in the underworld itself, that could bring that proud race to its knees. If the temple was never completed, it would serve as a reminder to whatever damned adventurer who found his way this deep into the earth - this was what killed the dwarves, so begone, lest ye suffer the same fate.
