The easiest way to explain is that a long time before I was ever born, a bunch of us did a thing and accidentally broke a constellation. [ And maybe this is why as much as he still doesn't understand why Venus Chose him, he can't really find her at fault. Destiny happened, and that's all it is. ]

Since we're all tied to the stars, that...caused problems, and here I am. It's...how do I put this, the constellation that broke represents "hidden knowledge", so now it hides all our fates from the rest of the world all the time. That's why people forget. [ Which is part of the reason why Day doesn't know where to begin to try addressing this. ]
