Well, at its core it's a tale about three brothers in all but blood and how their lives are changed forever by events greater than them, how they struggle against adversity to rise to the challenge these events present and retain their friendship amidst it all. The [i]Halo[/i] universe is just a conduit and catalyst for the story; it's used as a tool, not a foundation. That core is the only constant - anything else is periphery, at least in my eyes. You'll see how things develop, until then keep wondering and thanks for reading.
