Find some things around the house like beans, buttons, paperclips, etc. and place them on a piece of paper. Draw around them until you make a map. Name your new world and create a story within it.
Pictures of my world
Here are pictures of the steps I took and of what I used. I used my polished rocks and crystals. I didn’t write a full story, just a few ideas about the drawing of my map. But maybe one day I will return to it and write an actual story. But until then, here is what I have for this exercise.
World Name: Trinity
Trinity is a magical land that is cut into two parts. On one side lives the elves, humans, dwarves, and gnomes. They live in the West while in the East is inhabited by fairies, mermaids, merfairies, and nymphs. They trade with one another, and Trinity is a world of peace. Until orcs from another land on the other side of Trinity, that is not seen above, invade. They have to come together and fight the orcs together.
