In Guardians of the Galaxy (2014) Peter Quill lands on Morag with some device that let's him (I'm guessing here...) see the past as a hologram. He uses it to find the entry to a building, and finds the Power Stone encased in a metallic orb. He puts down a magnet, which allows the orb to be pulled from its prison and get sucked onto the magnet.
So, my question is, Quill seemed to know exactly what he was after, in terms of where it was. He also knew exactly how to retrieve it. Is there anything in the movie (or even in the comic backstory) that explains why or how Quill knew where the orb was, and why no one else had sought it? It seems like kind of a huge story hole when you take the whole MCU into account.
