The right one looks awesome.
By the way, there are plenty of things in Christianity that are "borrowed" from other religions. The date of Christmas, for example. Not 100% sure, but I believe that's also the date of some special worship day from another "pagan" religion. Just a little addition of the church to make the transition go a bit smoother for the survivors of their "holy" wars.
I so have different religions. Everybody bashes Muslims now because of a few terrorist attacks made in the name of their religion. Nobody seems to remember the countless people who died in the name of Christianity. Weird. That's why I refuse to align myself with a single religion. Isn't believing in "something" enough?
Oh crap, going way off topic. Lol.
So what's the role of this guy/thing in Diablo? Main villain or something? Never played any of the games. Only Starcraft and Warcraft. :/
