we were heroes (UNFINISHED)

In the world of dark academia, etc, two sides were separated. Two completely different worlds, separated by a dimension. Valeria, the first side, had rulers, elves, fairies, clairvoyants, heirs, royals, etc. Dystopia had hunters/huntresses, assassins, witches, vampires, werewolves, etc. they were in peace as long as one didn't talk to the other until one day, the dimension broke as they became one. the Valerians blamed Dystopians for the sudden cause as all of the sudden announced war on the Dystopians for killing Valerians for many centuries. they all go to war as an ex group of friends tries to stop it.. but who killed their son? Was it to the Dystopians? What happens in the war? And how many betrayals would a come..
