I'm not sure if this has everything to do with the house of hades but I want to bring it up nether the less. Do you people know what shape the protective borders of camp halfblood are? Because rain can't get in infering that the protections are a dome or box but Racheal Elizabeth Dare was able to fly over the borders infering that the borders are a tube or cube or whatever infering that the borders are open to the sky.
