THE GREAT FOREST
The Great Forest is the first Kalosian Province to be created after the Xelduinic Era. It was the first place the Kalosian Settlers were permitted to settle permanently in by the dragons, and Great Oak City was the first place ever to surface of the modern-day Kalos.
The province of the Forest has a lot of historical value if you're into that kind of thing. If you're not, it has a lot of frolicking-with-the-bunnies value.
It's ruled by Sylvanas, one of the original Kalosian Kirbies. She's a forest elf. She's a bit of a tree-hugger. Literally. Her motto is "trees have the best hugs, as long as you don't get splinters."
