I'm making an entire multiverse that every single one of my campaigns exists in, so I need help coming up with some planes to help flesh it out more.

So far I have:

• Lifeless Skyline
• Holy Playground
• Ouroborus's Eden
• Origin
• Starry Heights
• Death's Abyss
• Mechanical Mangrove
• Desolate Island
• The World Tree
• The Backrooms
• Flipside
• Celestial Dome
• Opposite World
• Amythest Abyss
• Vermillion Void
• Minus World
• The Acropolis
• [REDACTED]
• Caligneous Mantle
• ...
• Wastelands

I should make something clear: the planes can range from super silly to super serious
