how about we incorporate the personalities of the elements
fire loves to fight and just joins the war to kick a lot of a$$
water is mellow and wants to calm everyone down, even if it means forcing them into peace
air desires freedom for all the elements, so its fighting to prove that purity(mono) isnt the way to go
aether came from a different dimension and.... this one im just drawing blanks on
earth is stubborn and refuses to accept that any other element is better than it, so its trying to prove itself
darkness wants to take control of all the other elements and is fighting for domination
death just wants everyone to die
life wants to stop the fighting (very similar to water)
drawing blanks
entropy just loves watching people scramble around in a chaotic mess, and is doing everything in its power to continue it
light has the same goal as water and life
drawing blanks here too
