The pairing algorithm just shifts the bits halfway and then flips every other bit starting with the first one.
Idk how big of a character space I want but I want libraries / space areas to be navigable and homogeneous. I can work on heterogeneous algorithms later.
There's a significant amount of procgen happening via the languages and maybe fractalgen framework to make exploring more interesting.
Everything eventually terminates in these gigantic library complexes that eventually contain books with the specific page needed.
Transport networks would make exploration pretty great.
