"We've given them out to the mayors of towns too far to easily send runners. So far all we've gotten is two false alarms and a lone zombie, but it's still better to know about those sooner than later."
He hires more people. The best of his old hires get raises and assigned to teach the new ones things, including literacy. The big generator comes online and he starts selling candleless lights more cheaply, with access to the generator being a mere two copper per month. Radios and music-recording and music-playing machines are sold. Vats of polyester are brewed and spun with cotton into a comfy blended fabric that he tries to sell to tailors. He has a team of five scout and map the surrounding wilderness with a crude-by-his-standards scanner, looking for metal deposits.
The theater person who took the first batch of electric lights takes a music-recorder and starts selling recordings. Someone else buys a recorder and some recordings and sells recordings of the recordings, which annoys the theater owner so grievously that they have to take it to arbitration. Arbitration rules that no punishment will be leveled against the music pirate. The theater owner responds by declining to sell further recordings and simply holds "listens" of recorded shows at a discounted rate relative to live performance.
And his six month loan term is coming due soon, so he'd better stop spending capital on things. When the metal scouts fail to find any particularly good deposits for two weeks he recalls them and stops expanding his staff and just sells the things he already has.
Polyester is pretty cheap and becomes popular among the poor, and among those so rich that they can accentuate it with obviously expensive things and not risk being mistaken for poor people. People of reasonable means and uncertain status mostly steer clear. Lights become increasingly popular, although a lot of people conservatively just put one light in one room of their house. Radios are distributed (less rapidly than paladins on flying creatures could ferry them around) and used to communicate between towns; this winds up serving partly as a replacement for their ineffectual postal system and partly as early storm warning. The theater person starts playing the first halves of recorded plays and songs over the radio; people who want to hear the rest have to attend a listen.
He runs his stocks of materials low and gives some of his staff a few days off over their objections to make up the last three gold, and adds a silver to the moneylender's payment for her trouble.
When he's back in money he sends the metal-scouts out again, hoping to find a nice vein of titanium, iron, or at least coal.
He could just buy some iron the next time traders come through - there's a lull between the times when it might snow and when it already has, when it's impractical to use sledges and when it risks getting you caught in a snowdrift if you use carts, but it'll snow soon. He could even radio someone far away about his demand for iron. (This is pointed out by his obnoxious staffperson.)
Sometime between then and the first snow, one of his electricity customers electrocutes herself after cutting through the wires' insulation. Nick defends himself to law enforcement and arbitrators, talking about his warnings not to mess with the wires.
But that night he has terrible nightmares. Fires caused by electrical faults, explosions in the power plant, one of his employees screaming, his arm mangled under the bloody letters of the printing press...
The next night it's more of the same. Armies using the locomotives he was planning on building, nuclear technology in the hands of some unstable king. After that are dreams of being trapped forever, growing old and decrepit and dying of some sort of preventable cancer at the young age of 70. Dreams of his parents, laughing at how he fled from home but ended up stuck in one place anyway how pathetic.
Doxepine doesn't help. He's in a very, very bad mood by the end of the week.
Why won't these damn nightmares stop?! He's done nothing wrong, he's been careful, he's improving these people's lives by all accounts. Ugh.
He stops supervising his staff so closely and no longer comes out with new products. He runs out of doxepine. The nightmares stop, but the depressed, paranoid, angry voices in his head don't. He snaps at people who try to talk to him. He grumbles and delays when someone reports a problem with their devices or lights.
(It's only a matter of time before a little kid wants to see what's inside the wires -)
Obnoxious employee starts compiling radio news and printing it up for people who don't have their own radios.
(He's never going home, he's stuck with these ignorant primitives until his untimely death -)
The cartload of iron he ordered shows up.
(He might not even last to seventy, he could catch something from these filthy uneducated people at any moment and die, alone, while he slaughters a few million of the locals by electrical proxy -)
It's only when he happens to hear of a zombie attack on a neighboring village when he remembers that dark things exist. And one of the dark things that exist are woke shadows.
He scans himself with every still-operational sensor he owns.
He's just cracking up, that's all, his own mind is turning against him and if the medicine here is ridiculous the standard of psychiatric care is worse, he's just going to go steadily more insane until he hurts someone directly enough that they lock him away, and then every harmless thing he's tried to do will be dismissed as a madman's toys but that won't stop people from keeping things they can use to kill each other, no, practicality is always the ultimate concern there -
He forces himself to be angry at whoever did this to him, not himself, not the rest of the world. He storms up to the paladins' compound and asks the gate guard how they check someone for woke shadows.
