Arcane's Calendar, 589.
The first Astral War had ended nearly 600 years ago and the Arcane Kingdom had moved over and settled down for hundreds of years. With the exception of some older professionals, a new generation of the Arcane Kingdom had gradually forgotten about the Starsoul World, they only remember the Arcane World.
If the most prominent feature in Starsoul World was their Starsoul, then the most important feature of the Arcane World was the World's Guardian Trees, or in the entire Arcane Kingdom, the biggest feature was a variety of trees.
The world which belonged to the Arcane Kingdom could simply be called the world of trees or the sea of trees.
