If I remember correctly, the question was “why don’t the covenant want the halos in this one (Reach)” or “why aren’t they in this one” or something like that when we had just started playing.

So I went back and explained the history of the rings from 120,000iah years ago during the height of the Forerunners power, as well as where the flood came from, why the planet has only just been discovered by the covenant, and how the game (Reach) differs from the books and spoken lore established in games 1-3.

Funny thing is, I’m slightly wrong. He did technically ask me one other question, but it was an open question to the group “why do the Spartans look different except Jorge?” and I immediately went “are you SURE you want a full explanation?” to which others jumped jn and said “NO!” which was a little disappointing but not everyone enjoys lore dumps.

For a full explanation, read the forerunner series of books, the novelizarion of combat evolved, the fall of reach, the in-between book that tells us how anyone escaped to halo 2, and the Ghosts of Onyx. That last one isn’t super necessary, but it gives you a neat look at one of the Shield Worlds from the forerunner books.

I think lemmy has a character limit so I can’t get into a 3 hour typefest lmao
