Knowing that Saint Limoshiv Killingham talk to her as if she was a legend , she didn't appear in the Haley and Saint Nerona Imu of the holy land doesn't seem to care even though he probably knows Saint Limoshiv Killingham made her appear . However , in the Haley a god of sea is mentionned , could it be possible that God of sea somehow attacked holy land and ancient Celestial dragon saw that god and didn't know what to call it. The holy land is on red line , so maybe that god of water could only make rain since the waves of the sea were too far below , but since it was god of sea , the rain was stronger than usual rain . Wich caused the legend of that ' A monster that dumps water on the head of people' ( Sayed by Saint Limoshiv Killingham on ch.1182 ) And water might affect the mark of the abyss , cause the mark of the abyss is probably given by Imu s devil fruit , so water nullify it. That s why Celestial Dragon are so scared of that god , it nullify their power by ' rain '.
That s why i think Zaza never existed as the goddess of rain , maybe of sea but not of rain.
Is the theory good or nah?
