Ignorance is bliss.
Gaia is a world like our own, full of wonder and magic where anything is possible. Heroes with fantastic power battle criminal syndicates and fight in global wars for the sake of survival. To the average person, it might seem noble. Glamorous, even. Magic is a fantastic gift.
Don't look too closely.
If anyone has access to magic, war can erupt from any situation. No one is ever safe. Even the strongest magical powers can't keep the fragile peace for long or protect the ones you love. All the magic in Gaia can't bring them back - but it can avenge them.
