The definition of a low-fantasy setting varies from gamer to gamer but some elements are common to almost all definitions.
1.   "Monsters" are other. They, most of them, are outside the experience of most people. If the player-characters encounter one, it is almost certainly the first monster of that type that any of them have ever encountered. There are legends and tales but there are no blasé guidelines and little solid information.
2.   Magic is other. There are no magic schools and player-character mages either don't exist or have to hide what they are. Lists of well-defined spells, such as the one in our Core Rules, don't exist.
3.   Non-humans are other. The player-character's world does not include the usual elves, dwarfs and hobgoblins. If they exist at all, it is outside the cozy circle of civilizations.

What I am going to do in this brief book is go from chapter to chapter of the Core Rules and suggest how to modify the rules so that you can run low-fantasy adventures. Then, I will go though the Encounters book and do the same.
Because you will need the Core Rules, I am not charging anything for this brief volume.
