Hahha yeah I found that a fun name for them, I kind of imagine them to be sort of like Fear and Loathing in Las Vegas when they take the ether and go to the carnival.

I like the pheromone idea too, which is one I've been thinking of for a while bit never got a chance to write about or include in a story.

Yeah the idea of enhancements and cybernetics is one that has been around for a while, but I kind of like the idea of them being super rare, as if they're lost tech or something like that. In a way, it expands the idea that everyone living in these worlds are in an era worse than the previous one, but there are still echos around.
