Kellach is two-fold.
Discovery:
Essentially, he comes to Eorzea, and this is a completely new thing. He has to discover who he is truly without the shackles of his homeland's traditions, while still maintaining them in face of, well, a religion that is so overwhelmingly entrenched in Eorzeans' beliefs that it's difficult for him to do so. In addition to just discovering Eorzea in general and the history of his people that has gotten lost to time and is slowly crawling back up as he adventures in a land that is not his own.
Growth:
Meanwhile, Kellach has to grow as a person as he is relatively quite young at 20 years old - And he will continue doing so through relationships, both failed and successful, as well as meeting up with people, and his adventures. Throughout the year and a half I've played him, he stopped being an immature brat, but enjoys his freedom too much to abandon it.
