Eonil is home to many different types on Inhabitants. They have wildlife, critters, livestock and fish just like we have on Earth. Many of these creatures are probably naturally evolved with possibly a little help from Eonil herself but they aren’t magical by nature. Since these creatures have basically all similarities with the creatures here on earth I’m not going to describe them.
According to legend, Eonil herself used to be a goddess. It is therefore said that it is her energy that allows to use of magic and also possibly gave the other gods and later the people the means to banish the old gods from the planet. All creatures that are creations of the gods are therefore all magical.
