Mechanicum

Dalia had never been comfortable with tests, knowing she tended to clam up, and her mind go blank whenever she was asked a difficult question, let alone made to sit any form of exam. She often wondered how she'd managed to pass her transcription assessments.

The gleaming halls of the Magma City were spacious and functional, geometrically precise and machined with a smooth grace. Though there was utter devotion to function in its architecture, form was not overlooked and there was great beauty in the mechanisms of Zeth's forge. Menials and lowly adepts threaded the halls, chambers and cavernous workspaces, every one according Adept Zeth the proper respect as she passed.

Each new chamber brought fresh wonders of engineering and construction: enormous, cogged machines surrounded by crackling arcs of lightning; thudding pistons driving unknown engines and enormous caverns of steel where thousands of techno-mats toiled at bronze work benches on the tiniest mechanisms with delicate silver callipers and needle-nosed instrumentation.

At last they came to a wide chamber lined with rack upon rack of gleaming tools and fabrication devices that she could not even begin to name. A tall plan chest stood at one end of the chamber and four robed individuals stood around a workbench at its centre, each one shaking her hand and nodding as she was introduced to them.

First was Mellicin, a tall, handsome woman of middling years from the Merican continent, with smooth brown skin and a grafted augmetic faceplate over the left side of her face. She had been coolly welcoming, her remaining eye sizing Dalia up and down with the look of a professional assayer.

Next was a swarthy, stunted individual by the name of Zouche, a native of what had once been known as the Yndonesic Bloc. His handshake was curt and his brusque welcome had a hollow ring to it. Dalia was not tall by any means, but even she towered over Zouche. She estimated his height at no more than a metre.

Next to Zouche was a woman named Severine, who had the look of a teacher about her. Her hair was pulled into a tight ponytail and her pale-skinned features looked as though they might crack if her thin lips creased open with even the fraction of a smile.

Last was a smiling youth who went by the name of Caxton, perhaps a year or two older than Dalia, with a boyish face and a tonsured mop of unruly black hair. His features were open, and of all the greetings she had received his felt the most genuine, and she recognised his accent as having its origins somewhere not too distant from her own homelands, possibly the eastern slopes of the Urals.

With introductions made, Adept Zeth had lifted a number of waxy sheets of paper from the plan chest and laid them flat on the workbench in the centre of the room.

'This,' she announced, 'is one of the last great unrealised designs of Adept Ulterimus, developer of the Sigma-Phi Desolator Engine. Data appellations name it as a theta-wave enhancer designed to stimulate long-term potentiation in humans.'

Ignoring their blank looks, Zeth continued. 'It has been transcribed faithfully by the tech-archivists of Ipluvien Maximal from the data fragments recovered from Adept Ulterimus's tomb below the Zephyria Tholus, and you are going to build it. You will have access to workspace, tools, materials and servitors to perform the manual labour. Within seven rotations you will demonstrate a working prototype.'

With that, Adept Zeth had departed with a swirl of her bronze cape, leaving the five of them alone in the workspace.

The first day had been spent in working out what the device was intended to do, no small feat in itself, given that the transcribers had been literal in copying out Ulterimus's spelling mistakes, corrections and the exact shape and texture of his many crossed-out workings. Sketched images and rough diagrams scattered throughout the plans gave some clues to the device's function, but it was a painstaking process just to divine what requirement this unrealised device was intended to fulfil.

A pecking order had quickly established itself within their group, with Zouche and Caxton deferring to Severing who in turn took her lead from Mellicin. Dalia found her place within that hierarchy when she alone was able to decipher the notes and diagrams enough to understand the device's purpose.

'It's a machine for enhancing the communication between neurons in the brain,' said Dalia after a frustrating hour of unravelling a thread of randomly scrawled notes. 'According to these notes, Ulterimus seemed to believe that a process known as long-term potentiation was what lay at the heart of the formation of memory and learning. It seems to be a cellular mechanism of learning, where the body is induced to synthesise new proteins that assist in high-level cognition.'

'How does it do that?' asked Severine, looking up from redrawing the circuit diagrams and synaptic flow maps.
