Planes were different space-time dimensions that were connected to each other. Apart from a few connection points between planes, they all had their own unique natural laws.
For the adventurers of Arthur, after reaching a high level, such as having the fifth-circle divine spell " Otherworld teleportation, " they could go to the bottomless abyss to save their imprisoned friends or set sail on the shining water of the sea god River.
They could go to the garden of Joseph to drink and taste wine with the kind giant, visit and search for Sage giszera in the sea of wonton, or go to the city of ten thousand doors, the city of imprint, in the harmonious outer realm, to see the many schools and even the most mysterious legendary Lady of Pain with sharp hair.
It could be said that without going to the other world, one could not be considered to have experienced the real adventure Life in Arthur.
