The Journey of the Rainbow Dragon

If you were to travel across the planes, where would you choose to go?
The elemental plane of fire that is as welcoming as fire and feels like home?
An abyssal plane with simple folk customs and numerous geniuses?
The Titan plane with its outstanding people and beautiful scenery?
In this regard, Ron, who had just been reborn as a rainbow dragon, said
"I don't want any of it!"
