Hey guys, I copied from what Aaron said. These are some ideas to use when you create your planet. You can stem from these or ignore them completely, just keep in mind your character’s view of things. Good luck!
1. Does my character’s planet support life? What is the atmosphere like? The animals & plants? Is it covered mostly by water or by land? Does it have any moons?
2. What is the planet’s civilization like? Is it industrial, covered with cities, or natural with the character’s species living in harmony with the ecology? What is the main language spoken? Any government? What sort of music does my character listen to?
3. What are the things my planet has in abundance which my character can offer to others? What are some things my planet needs to be improved?
