Kathy's Brockton Bay Adventures is the story of an SI with the Tinker of Fiction powerset. The powerset makes you switch between different fictional universes between 1-3 weeks and allows you to build tech that can emulate things from that specific universe.
@Monk Penguin is the creator of this concept in his Quest Tinker of Fiction and I am writing and SI that has the same powerset, I already have posted this as omake in his quest but it evolved into its own thing so now it gets a thread...
Yay, another Tinker of Fiction! It's like we don't have enough of these stories, right? I'll tell you I put a little twist into the story, will that pique your interest?
I have a Plan, now on Sufficient Velocity
