I gave you the wrong answer yesterday but saw a reddit post now asking the same question so remembered.Another thing I'm confused about is certain enemies drop these floating relic type artifacts. There seems like something needs to be done with them but if I just leave them then I recover them at the camp provisions area. Am I missing something there?
Is this what you are talking about?

Its Abyss Power Cores. Grab them with Axiom and then press the button (Y on Xbox controller for example) to automatically put it in your Kuku Pot. Its crafting mats.
Do you have a Kuku Pot? Its a chapter 4 quest and can't be missed. Can only store Abyss items in it. Very useful when doing repair puzzles as well. Like when you need to gather 3x pieces to repair a machine you can just go and get them all and then take them out in front of the thing that needs repairing. Without it you'll have to grab it with Axiom and them manually walk back each one.
Kuku Pot is also how you eventually craft the best gear in the game btw.
