Knowing what the innusannon or arthenn look like are not important to the story (only provides image appeal)

knowing who made the crucible first is somewhat important but not entirely. A previous cycle made it, they died, plans survived, repeat. Thats all that you need to know.

the keepers is meh, we know what they were meant to do but it's not important they're just maintenance now.

adjundant virus origins are from the Cerberus using the tech gathered from the collector base it was explained.

and seriously you want to know the info on the navy, army, government, home world, and species of the time. Ill let Javik answer this one. "We are dead now, what does it matter?"
