Hey, if you have no choice but to infodump, always use characters, never the narrator to tell things to the reader.
This way, if you got something wrong and someone points it out later, you can argue that this character in particular was lying/misremembering/was ignorant of the exact details. You, the author, obviously knew what the real facts were all along.
