The Voreal Kingdom could be considered as unique to say the least.
There were no walls like the Amethyst Kingdom and the Aurora Kingdom, instead, the whole kingdom was surrounded by a natural mountain range and each of the mountains easily dwarfed mount everest.

First of all, the siblings realized that all the beasts there were intelligent and could speak without any issue, which was quite strange considering that all the beasts they usually saw would try to kill themm on the spot.
They were also confused by this since according to their knowledge, beasts only develop proper intelligence at the diamond rank and can start speaking at the platinum rank.
