Okay many of u guys have heard of the story Atlantis. Neptune went to sleep for many years, but he had 7 son, and they made their empire evil, so when Neptune woke up and seen what his son had done, he destroy Atlantis with a giant wave/earthquake.
Remember in the beginning of SoN Juno zei the son of Neptune has been asleep for many months. Also in the SoN cover it looks like Atlantis sink/falling like in the stories. Also it strange how the atlantean called the god door his roman forum like the Romans at camp jupiter.
It kinda connected, but we'll wait and see.
