If you wish more feedback, in Vivid, Hidden and Ancient Groves tabs, in upper left part of each page don't be afraid to use an occasional hyphen – more than one for a such short paragraph would probably be too much, but 'untouched' in Vivid Groves could have used a hyphen.

In 'Remarkable Trees', The Emptree, in line '...of serenity. Inside no' you might try to put 'no' on a lower line to create a shorter and less jagged line. When you use Align Left/Ragged Right text alignment you generally wish to avoid lines of noticeably different length and keep them as close to a block as you can. 

'1d3 sample ideas' lines look a bit redundant – in a such short and well-organized publication it is already clear what each 1d3 table is. Instead this line could have been used for something like 'Sojourned visitors to the grove', to add more mood.
