Nobody knows about my planet ever since I came, the lore, countless princesses/priestesses I mustered for the inevitable disaster, and exact origins of where we come from, and I like to keep it that way.
The outside world still does not know very much about me until they seriously start dreaming of going there and ask them around. Eventually they will reveal who we are and why we came to Earth from the future in the first place.
I am generally very sneaky and yes, I do hide my huge power potential. ;3
