“Mr. Hartley is an archeologist.
Do you remember that strange, famous guy that disappeared years ago as he tried to prove the existence of Ancient Earth? The one that got the government’s permission to voluntarily visit Tartarus and never returned?
Well, it turns out that he wasn’t killed by space criminals like we all thought. He just stayed here because he wanted to.
He spends his time digging up obsolete artifacts from the trash, trying to interpret Ancient Earth’s culture through them.
(Yes, according to him it really existed. Their weird house is supposed to be a theoretical approximation of an Earth house. He’s completely bananas, I tell you).
(He’s a pretty nice man, though).”
