"I fear this country is done for our kind." The vampiress looks around the other occupants of the tavern room, a glass of scotch gripped in her hand. It's not her favourite thing to drink, but it's a distant second. "I've managed to eke out a decent life for myself as a hunter since I turned, but things have been getting harsher since my children's birth. Technology is progressing in tandem with the humans' ability to harm us. It's on a matter of time before every household in the kingdom has a sidearm that can put an end to us."
"What's the problem?"
"This is a... Grishom and Clems boiler? I've got a hunch. Let me have a look?"
"Ah... It's these stupid thin snaky feed lines again. They pinch way too easily. Do you have any quarter-inch copper pipe?"
"-I'm not quite sure I should confirm or deny that. Close the fuel feed for this boiler? I have to take out this line and replace it with a wider one."
"Some of us don't even eat people occasionally," he mutters. And gets to fixing.
"Uhh. Not sure what to say to that." How fascinating. Not. CLANG. CLANG. "Do you have a metal shop onboard?"
"Good to know. Don't need it - unf - yet. Do you use electric batteries or pressurized air for submerged power?"
He doesn't really need a blowtorch to weld copper, thanks to what little magic he's mastered. Welding sounds come from where he's wedged into the boiler.
"Good. Old batteries are treacherous bastards."
"No, really. They'll give up their voltage potential on you or explode or randomly start leaking acid at the worst possible time just to spite you. Or perhaps I'm biased."
"There's some interesting stuff coming out of Thames Yard, they're using exotic metals to get more power out of less weight, but they're still the devil to build safely."
With a final clang, he hauls himself out of the boiler. "Okay, valve back on and let's see if it stays lit with this newly fitted custom feed line."
Teddy uses a flint to spit sparks at the pilot light. It flickers as wildly as before for about ten seconds, then stabilizes. "There we go. More pipe volume makes it take longer to start up, but it least it stays on now. Everything look good there to you?"
"I'm Teddy, and I've never met Satan or any of his friends."
...He holds out his left hand nervously for a handshake.
"Not if I have anything to do with it we won't. I think I want a look at this 'mystery mold. Oh, and it's Teddy."
