Maybe. I would like to continue Zendaria story more in future updates, also perhaps I'll add more small details in the early game so Zendaria appears earlier into the story, thanks for your recommendation.
NP.
You can always make minor things like the Bird man(zendaria servant) giving to you the Thunder magic book to you before without expose his identity. Zendaria would appear later and basically it would be the same but the book would already be in your hands.
Or this bird guy appearing few times(before capture you closely to the forest) like observing you or making minor things(like scare a enemy) while Micah notices about it.
