Here come the angel and the devil to play. Both tasked with observing the world around them for reasons they don't begin to understand. They come with all of their might altough their aproaches are different
The angel prefers to observe,, armed with a whip oof holy light, flight and a glamoured roll of newspaper (Its meant to swat the devil when she is being too cheekytowards her) she tends to act in a colder manner altough she has hidden warmth
The devil on the other hand. Armed with her pitchfork and a talent for pranks and missconducts likes to have fun (And don't tell the angel she enjoys when the whip gets used)
Both are able to summon stuff at their own whims. And the nature of the world has changed them so they would be able to exist. No longer being pure beings of their own alignment they can learn and grow
