So, I noticed @RuxALT has been telling facts that NO-ONE ever knew, so thank you to them, because I still don't know how I don't know that Annabeth Chase's name is Annabeth Chase.
But this next fact is a sad one. Because, Percy cannot have Riptide in New Rome. He and Annabeth want to live there together, but in SON, Terminus did not allow him to bring Riptide into New Rome when he was going to the meeting about Frank's quest. So, even when they live there, he can't bring the Sword. I know this doesn't seem very big of a deal, because there probably won't be any threats, (Of course, you never know. The Demigod world is crazy) but still, it's Percy's signature weapon. With him since The Lightning Thief. It will be kind of sad that he will not have it again when he becomes older. So, once again, Percy cannot have Riptide in New Rome.
