I had Rosetta mention her origin several times. Things about it (like Index). If you’re not sure what’s going on don’t sweat it. It’s not super important. If you WANT to follow up you can read Rosetta’s origin in the retro dojo section. If you’re not really that motivated, don’t worry. It’ll all come out again. It’s good stuff and explains all the spiral shinanigans, but not totally necessary to enjoy the read.
