Humanoids are species that have a similar physical form to humans but are genetically different species. Humanoids will often have subtle differences in features to humans such as different ears or teeth or may have extra body parts such as tails.
There are several humanoid species encountered throughout the game. The first such species is encountered in the Misty Forest in the village of Luc. These humanoids have tails and horns but after crossing The End of the World the party meets many humanoids, but the only physical difference from a normal human is usually their pointed ears.
