I’d like to check out

• a world similar to our size but that has only one country/kingdom/etc
• a world that never had wars/always lived in peace
• a world that had teleportation unlocked and where it would be as easy to use as walking
• a world that had invented an item that lets you “store” and “read” feelings (you could read other’s feelings too)
• (golden compass) a world where humans/all intelligent species would have their souls as creatures that followed them in life
