Some of this stuff seems a lil' inconsistent so ill go ahead and explain:
Ama didn't die until after the war, but it wasn't so soon afterwards that she did. After Akesios followers lost she had the idea to do something drastic that made her all powerful basically, and they had an epic battle that lasted a long time before Ama finally overcame Akesios and sealed her away within herself, doing this made her die (and turn into a giant crystal) but also trapped Akesios within her. Akesios's influence is able to seep out due to cracks in the crystal though.

And also, Ama created every world except for the five Asterisk created. It was Aster, however, who connected them and made it so ronde can be used to travel between them. She also created a couple of smaller dimensions just 'cuz. One she created was to hold her Guardian Statue. I forgot to mention them in here but like.....they're these giant statues that the gods erected. You can find out more about them on one of the drawings in the #bookofaionia tag.

also funfact, all the gods were very young when their stories happened!! They were just teenagers. They used their magic to make themselves look older tho. I've been planning on drawing how they make themselves look vs. how they really look for awhile now....
