When Nature Calls!
While we have no Pet Detectives in this, we do have a lot of other options for those who heed the Call of the Wild!
Gathered within, written by Kalen Tessmann and with a cover by William Timmins, you'll find a host of options for the Druid class. Want someone who likes mushrooms and fungus? We have that. Want more options for using magic and controlling Ley Lines, we have that as well. We even have a Giant Tree Squirrel and a Riding Kiwi!
You should check it out. :)
