The Endless...

I'll keep this as spoiler free as I encourage anyone who hasn't to go and read Edge of Dawn. But in the epilogue there is a monologue called the harbingers lament, which not only to me, explains the Endless in an extremely satisfying way but turned them into the most interesting new faction the series has. Plus it is written in extremely stunning prose. But is this just me, are others as excited for future stories surrounding them?

PS... Halo is absolutely a book series as much as it is a game, if you disagree, grow up, go read a book. Nerd.
