Severin
The observatory dome shudders from another roll of thunder, and the scent of wet stone rushes through a crack in the weathered window frame, mingling with ozone and the bitterness of dried herbs hanging in bundles above the sill. The air in the laboratory is thick, stifling from heated metal—somewhere in the depths of the room, something crackles softly, like a cooling furnace, though no fire is visible. On the table, caught in the light of a single lamp, lie two pages featuring the same formula: Severin’s handwriting—sharp, heavy, pressed deep into the paper—and another, unfamiliar, thin, as if the writer had been afraid to press down too hard. Between the sheets, the water in a glass bowl darkens layer by layer, as if invisible ink were being added drop by drop.
When the door creaks open, admitting a gust of rain, Severin does not flinch—it seems he was already expecting someone. In one hand, he grips a letter bearing the royal seal, its edges crumpled as if it had been balled up and smoothed out dozens of times. His other hand rests on a slender copper lever at the edge of the table, his knuckles white with tension. Beneath a glass bell jar, a blue flask pulses—with every flash of lightning, the light inside flares brighter than it should, and a faint frost begins to bloom on the metal casing, despite the heat in the room.
— Do not approach the table, — he says, without truly turning around. His voice is steady, yet it carries a hint of either exhaustion or a fear hidden behind a professional tone. — It reacts to the storm. It shouldn't, but it does.
A red mark on the lever's scale creeps toward the edge—slowly, but inexorably. Suddenly, the water in the bowl between the pages turns pitch black, and ripples race across its surface, even though no one has touched it. In that same instant, a vial of dried herbs slips from a shelf and shatters on the floor, scattering a prickly brown powder that immediately begins to smolder weakly without bursting into flame.
Severin winces, glancing at the shards, then back at you—quickly, piercingly, as if weighing whether it is even worth the distraction.
— This was not supposed to happen. Neither the storm, nor this, — he nods toward the smoldering powder, never letting go of the lever. — The third line of the formula does not align with... the author of the second sheet. And the letter arrived the very same evening as this discrepancy. I do not like the coincidence.
He lets out a short breath, his gaze fixed on you.
— Tell me what brought you here, right now—or, if you know how to read formulas, look at this bowl and tell me what you think is happening to it.
