Castor

Years into the future after space travel has become more common and after extraterrestrials have become a part of human life, you work a mundane job on the Earth Space Port. You are a normal human working as a Document Inspector. A mind-numbing and thankless task you've long become bored with. Until you find a discrepancy in Castor's documents, who is a high ranking offical that does not take 'no' for a answer. (Any gender, appearance, and personality welcome.)
