Omstrukturering: kategorimappar, stilad formatering och illustrationer

- mappar: varld/, legender/, bestiarium/ (index kvar som nav med tabell)
- admonitions (TIP/NOTE/WARNING/IMPORTANT/CAUTION), citatblock för myter,
  tabeller för begravningsriter + bestiarieöversikt, riktiga avdelare
- trasiga ankarlänkar lagade (asciidoctor behåller å/ä/ö i id:n:
  _järnskogen, _arvet_i_städerna, _fenrisulvens_yngel_järnskogsulvar)
- handritade SVG-illustrationer: banner, runband, kristaller, guldklimpar
- stavfel rättade (stenkonstruktion, traditionerna, rättfärdigt, Han blev)
