All four plummeted into blackness — Kali backwards with the things clinging on to her front — falling helplessly amidst countless shards of the partly shattered dome. Under different circumstances Kali might have found the susurrating crystal rain surrounding her mesmerising, but she was too busy bracing herself to hit the ground beneath the dome to pay much attention. No impact came, however, and she realised the dome must enclose something more than the forest floor itself — but what? For a moment she forgot the rope, imagined herself plunging ever downwards into some unknown abyss, but then the rope reached maximum length and she came to a halt with a whiplash jerk that made her internal organs collide and winded her worse than the folding bastards had moments before. Those same things, which until that moment still clung tenaciously to her front, triangular maws trying to snap at her face, were wrenched from her and tumbled away screeching, down and down into the dark. Seconds passed and then she heard the sound of three impacts from somewhere far below.
Kali groaned and hung where she'd halted, limp as a discarded doll, rotating slightly, the rope creaking above her in the silence that followed the fall. A dot in darkness, her head flopped backwards, she stared down into a vast and circular subterranean chamber lit vaguely by the half-light penetrating the broken dome. Whatever the place was, it seemed deserted and utterly still — the only movement motes agitated by her intrusion bouncing in the air — and the centre of it was dominated by a strange, shadowy mass that the whole structure seemed to have been built around. Also circular and broad at the base, but tapering gradually with greater and greater height, it rose towards her from the chamber floor like some huge ant hill — a hill within a hill — ever upwards, almost as far as the lip of the dome itself. It was a dizzying sight, especially when viewed upside down, and while Kali hadn't the faintest idea what it was, she did know she wanted a closer look.
The air in the chamber — old air, the kind she liked — acted on her like smelling salts and she snapped to, realising she had to find a way down from where she hung. But that was going to be easier said than done. Even if she whistled Horse to the edge of the dome, the rope on which she dangled was nowhere near long enough to reach the top of the mass, let alone the chamber floor, and unless she was going to be happy taking home memories of a bird's eye view of… wherever she was, she was going to have to find another way to descend. She pulled herself upright and turned on the rope, eyeing her surroundings, and had gone almost full circle before her gaze lit upon what looked like a platform, metal and ornately railed, running like a stretched-out horseshoe along the curving upper chamber wall. Some fifty feet away and below her, it would do as a start. It looked like one hells of a jump, however, and in taking it Kali knew she'd be committing herself to a descent with no return, because there was no way she'd be able to reach the rope again.
But she hadn't come all this way for nothing, and as Horse was probably getting a little disgruntled holding her dead weight, why not do him a favour and lighten his load? Besides, whoever had built this place must have built it with a front door, and in her experience of these old sites front doors were always easier to find from the inside than from the out.
Decided, Kali detached the rope from her belt and began to swing back and forth, building up an arc of momentum that would allow her to make the jump. She continued to swing until she had reached her desired speed and apex, and then with a determined cry let go of the rope. She flew, arcing through the air and then dropping, and landed hard on the platform, rolling to lessen her impact. Lessened or not, there was an eruption of dust and a loud metallic clang that echoed around the ancient chamber, quieting only after Kali thought she might go deaf. She very much doubted anyone was home but, if they were, they now sure as hells knew she'd come to visit.
All remained still and Kali stood, cautiously at first, but then, realising what she stood upon, throwing caution to the wind and instead grabbing the ornate railing to stare down, amazed. Still high above the chamber floor, the platform was clearly built for observation, and what it observed was the strange mass that dominated the place — the hill within a hill. Only it was no hill, she could see now, but a huge and vertiginous, winding metal stairway.
Kali swallowed because it really couldn't be anything else.
She was looking at the Spiral of Kos.
It was as incredible as it was mystifying. Overlooking its summit — still impossible to reach from where she stood — the dizzying structure was constructed in the same ornate fashion as the railing on which she leant, the steps of the stairway itself spiralling up inside a superstructure composed of flowing and curving ironwork the likes and artistry of which she had never seen. What drew her attention more than anything, however, was where the stairway led. Because there, at its top, completely isolated from the rest of the chamber, was another railed platform, and on it a large metal plinth.
And resting on the plinth was a giant key.
A key! Oh, she loved keys. Kali had no idea why it was there, where it had come from or what it unlocked, but she was certain of one thing — she wasn't leaving until she had it in her hands.
She turned, meaning to find a way off the platform and down to the first of those stairs, but as she did she caught a hint of movement from the Spiral itself. She turned back and squinted. Her eyes more adapted to the gloom, she noticed for the first time that the superstructure had apparently once housed some kind of hanging garden, for the dry and neglected remains of plants — thick tendrils and a number of presumably once-corpulent pods — still draped it now. That explained things. Perhaps one of those had shifted slightly in a draught from above — or then again, perhaps it had been nothing. A trick of the light.
Kali moved off the rail, searching for the way down that had to be there. Oddly, though, she found no connecting walkways, no ladders, no obvious way off the platform at all other than a small gate that led to… well, she wasn't sure what it led to. But as she walked closer, she felt a glimmer of recognition. The gate led to a cage, large enough that she could, if she so wished, step inside and which had a single entrance-cum-exit. Though it was different in many respects — more ornate, more complex, more mechanical-looking — it was clearly a version of the devices in use in the more industrialised areas of Vos — hoists and pulleys that had once lifted warehouse materials but now lifted men. Was that what this was, then? A… lift that could transport her off this platform? If so, where was the rope or chain suspending it? Curious, she leant around the edge of the cage, examining it more closely, and saw that though there was nothing to suspend it from above, the rear of the cage was secured to a thick metal arm that rested in the upper of two wide recesses in the chamber wall, recesses that swept away and down the wall in a reverse spiral to that of the Spiral itself, vanishing into the shadows below.
It had to be the way down. But after ages of disuse, could she trust it? Would the thing even work?
There was only one way to find out. Kali opened the gate and stepped warily into the cage, feeling for any kind of shift beneath her feet, all too aware that under the suspended floor there was nothing but a long, long drop. But she found it solid enough and so turned and closed the gate.
Kali waited. Nothing happened.
She waited more, and still nothing, and she frowned. Then she spotted a dust-shrouded lever on the wall of the cage next to where she had entered. Some kind of switch? Swallowing, she laid her hand on the lever and pulled it down. There was an empty clank.
