The book of the month for Season 2, Episode 2 is any book on worldbuilding or use a site like World Anvil or Campfire.
What is worldbuilding, and what goes into it? A lot! Instead of a book of the month, we recommend you play around with a worldbuilding program. Our favourites are World Anvil and Campfire, and both allow you to set up a free account and play around. Take some time to see what worldbuilding entails, and have some fun while you are at it. Just don't get overwhelmed, not all aspects need to be included in each story. We will discuss how we build our worlds in the next episode.
