deep (in more ways than one) dive into the lore of the Pathfinder games, in a pretty compelling (and sometimes dark, also in more ways than one) story.

you may want to have the Pathfinder Wiki on hand when reading, especially to figure out where specific named locations are, as Eando does wander through quite a lot of geography. though do be aware that if you look up the main character (or some other articles) you may find spoilers.
