Story
There is a kind of Hunter who answers a Horror not with a gun or a prayer, but with a question: what are you? We call them Alchemists. Half of them should have been chemists. The other half should have been burned at a stake. Most are a little of both, and proud of it.
Alchemy is not the polite science of clean rooms and humming machines. It's much older and rude about it. It is symbols chalked on a workbench, a crucible that smells of lightning, and the stubborn belief that nothing in this world is impossible if you understand it well enough. Lead into gold is the child's play. A real Alchemist will tell you the metals were never the point. The point is that reality keeps receipts, and they have learned to forge the signature.
That belief is also the trap. To learn what a thing truly is, you have to understand it, almost sympathise with it, and a Hunter who stops flinching at the Horrors tends to keep walking until there is nothing left to flinch at. I have watched brilliant people lose themselves, chasing answers until only the work remained.
I learned that watching Dr. Elara Rutherford. She could read a haunted grimoire and a doctoral thesis with the same flat patience, it all seemed like second nature to her. When we were working together I saw her dissolve a charging Horror into a puddle of rancid goo with a single vial from her pocket, then thicken the air in a doorway into a wall of shimmering glass so the rest of us could run. She didn't even raise her voice.
But genius like that runs hot. Elara would vanish into her work for a week and stagger out of her lab looking like she had been the experiment. She forgot to eat. She forgot my name twice, and I had been standing next to her the whole time. The secrets of the universe were always more real to her than the people in it, and that is the curse stitched into every Alchemist's coat. The transmutation does not stop at the bench. Given long enough, it comes for you too.
The ones worth fighting beside are the ones who keep a tether to something human, a person, a habit, a reason, anything that pulls them back up when the abyss starts looking back. Hold that tether and there are few allies more valuable. Lose it, and you become exactly the sort of thing the rest of us are called out to handle.
So when you are facing something with too many mouths and not enough mercy, hope an Alchemist is standing next to you. Sometimes the only thing between your crew and oblivion is a vial of shimmering liquid and the magnificent lunatic brave enough to have brewed it.
A word of advice, earned the hard way: if your friendly neighborhood Alchemist ever starts to glow and lift gently off the floor, that's your cue to be somewhere else. Call it basic workplace safety.
