Hello Van Davis, thank you for checking out Wilderlands and giving your thoughts! To your question on spells and wizards, for the initial release on the book I wanted to focus on creating a game that could feasibly play directly in Middle Earth, where the only wizards are named characters or far away to the east. However, some of my playtesters have pestered me to create some kind of wizard supplement in the future, and I am tempted as more people ask as a separate PWYW publication.
On the context of the spells of the enemy, Tolkiens heroes often fought against the sorcery of spectral foes such as the Barrow Wights and the Witch King. Tolkien also has a great passage differentiating the Art of the Elves from the sorcery of the Enemy. Thinking on your point, I could have included a spell caster villain in the bestiary to make this point clearer! I do have an adventure in mind with a spell casting villain, and I will be sure to include how they are “different” to the Songs of the free peoples in that publication.
If you have any other questions about the game or future releases, please reach out.
