I didn't set out with a Kain shrine in mind- I saw that Quantum Leap, Alex of jowy.net's well loved Kain shrine, was up for adoption. I had been wanting to make a Final Fantasy IV shrine for some time. I had originally planned on Cecil- Cecil and Kain are my two favorite characters, and there were already a few shrines to Kain and none (alas!) to Cecil. I quickly changed my plans though, to take over this wonderful shrine.
But why Kain? To start off- he's awesome. It comes with being a dragoon. But more importantly, he is influential. Kain's the original antihero of Final Fantasy. He doesn't talk too much about himself, and he'd prefer to keep it that way- and his reluctance hides deeply human desires. Final Fantasy IV was probably the most influential game in the series, and to me, the most important. There aren't very many sites left that cover this wonderful game. And in the words of the original owner:
I find Kain to be someone that I can strongly relate to, especially the way he is constantly struggling to find who he truly is. I think that's a conflict we all face, and I like the way Squaresoft portrayed that through Kain.
Kain's a character that a lot of people identify with, beyond the "bad-ass" moral ambiguity factor. It's hard to be good, and I think with Kain, Final Fantasy IV did a good job adressing the light and dark in each of us.
