Actually that is incorrect. The initial Battle of Earth seen at the start of Halo 2 was the Prophet of Regrets own fleet known as the Fleet of Sacred Consecration which stumbled upon Earth or as it was known to them by the lumaries Erde-Tyrene during the age of the Forerunner Ecumene. We see in one of the terminals; I believe the Halo 2 Anniversary terminals that the Prophet of Regrets discovery was purely accidental.Ahhhh,yes I am.In the book 485 ships were destroyed and the 15 you see in halo 2 that invade earth are what's left from that initial 500.They still had a significant amount more as you can see in the cutscene after chief kills the prophet of regretI think you're confused by the timelines. Apparently the 500 ships were destroyed BEFORE Halo 2.In those 485 ships you speak of were destroyed in the novel halo first strike,idk if those are the same ships you see during halo 2,but I'm assuming they were so it's kind of common senseObviously people don't understand that because I have like 4 or 5 different people claiming otherwise.I think you misunderstand how smart people can be.If you play halo 2 and see all those ships you see a battle taking place around high charity,so people obviously realized that the covenant fleet is significantly less
A.) Too small for the prophets to care about
B.) Not the largest fleet in existence

Do not call me ignorant or misinformed when you guys are the ones ignorant and misinformed.
Also, my point isn't to trash on the books. I'm sure a lot of the books are fine, some are probably even fantastic. It's just that a lot of points in the books take away from the legacy and legitimacy of Halo 3 and the original saga. These books are meant to tell good stories but these stories sometimes interfere with the story that almost everyone cares about the most: the original trilogy.
The remaining ships gathered of the original 500+ ships at the Unyielding Hierophant would later reinforce the Fleet of Sacred Consecration shortly after the Prophet of Regret was forced to flee New Mombasa and as seen in Halo 3: ODST the Brutes began executing the Elites and I believe additional fleets also participated which eventually led to the near total annihilation of the Home Fleet by Halo 3.
