By popular request, I put together an animation of the realm data as I did for worlds 9 and 11. Here it is:
Same caveats as every time: This is just put together from debugging data, so there's no persistent coloring, no legend, no backdrop map, and some data is missing here and there. In particular, at 1:59 I changed the plot format in the maps and didn't update this tool to read the new format again until 2:07. This time it does actually start from the beginning though.
