The mage scrambled back to the others. He had to lean close to be heard above the endless roar. 'There's caves! Only the wind's plunging down their throats – I suspect it's cut right through the hill!'
Heboric was shivering, beset since morning by a fever born of exhaustion. He was weakening fast. We all are. It was almost dusk – the unrelieved ochre dimming over their heads – and the mage estimated they had travelled little more than a league in the past twelve hours.
They had no water, no food. Hood stalked their heels.
Felisin clutched Kulp's tattered cloak, pulling him closer. Her lips were split, sand gumming the corners of her mouth. 'We try anyway!' she said.
'I don't know. That whole hill could come down—'
'The caves! We go into the caves!'
Die out here, or die in there. At least the caves offer us a tomb for our corpses. He gave a sharp nod.
They half dragged Heboric between them. The cliff offered them a score of options with its ragged, honeycombed visage. They made no effort to select one, simply plunging into the first cave mouth they came to, a wide, strangely flattened tunnel that seemed to run level – at least for the first few paces.
The wind was a hand at their backs, dismissive of hesitation in its unceasing pressure. Darkness swept around them as they staggered on, within a cauldron of screams.
The floor had been sculpted into ridges, making walking difficult. Fifteen paces on, they stumbled into an outcropping of quartzite or some other crystalline mineral that resisted the erosive wind. They worked their way around it and found in its lee the first surcease from the Whirlwind's battering force in over seventy hours.
Heboric sagged in their arms. They set him down in the ankle-deep dust at the base of the outcropping. 'I'd like to scout ahead,' Kulp told Felisin, yelling to be heard.
She nodded, lowering herself to her knees.
Another thirty paces took the mage to a larger cavern. More quartzite filled the space, reflecting a faint luminescence from what appeared to be a ceiling of crushed glass fifteen feet above him. The quartzite rose in vertical veins, the gleaming pillars creating a gallery effect of startling beauty, despite the racing wind's dust-filled stream. Kulp strode forward. The piercing shriek dimmed, losing itself in the vastness of the cavern.
Closer to the centre of the cavern rose a heap of tumbled stones, their shapes too regular to be natural. The glittering substance of the ceiling covered them in places – a single side of their vaguely rectangular forms, the mage realized after a moment's examination. Crouching, he ran a hand along one such side, then bent still lower. Hood's breath, it's glass in truth! Multicoloured, crushed and compacted ...
He looked up. A large hole gaped in the ceiling, its edges glowing with that odd, cool light. Kulp hesitated, then opened his warren. He grunted. Nothing. Queen's blessing, no sorcery – it's mundane.
Hunching low against the wind, the mage made his way back to the others. He found them both asleep or unconscious. Kulp studied them, feeling a chill at the composed finality he saw in their dehydrated features.
