The 10[i guess kinda 11] civilized races of people in Arcadia:
Humans[ex. Buster]
Cats[ex. Limey]
Frog [ex. Fissure]
Demon [ex. Walnut]
Giraffe [ex. Yoshi]
Bear [ex. Bear]
Possum [ex. Possum]
Rabbit [ex. Tara]
Ghost [ex. Metallu]
Alien [ex.Olas]
Plant [ex. Vash]
the 11th i can't say cause it would spoil the last 45% of the game.
