Headcanon Guides

These are the longer notes that did not fit on the generator page itself: where a headcanon generator gets its lines, why it repeats, and how to check what it does with a name you type. Every number quoted in them was counted from this site's own source file, not estimated.

The tool behind all of this is one HTML file with a fixed bank of 180 hand-written lines and no model of any kind. If you only want to roll some lines, the generator is one click away.
