I pick no nation, i prefer there are a new group which not bound to any countries.. let's say we make it into 3 group...
1 group which stands to Dharma, 1 group which stands to Chaos, and 1 group stands for the balance between chaos and dharma... and each group have at least 9 True Runes (and the halves one) at their sides..
Dharma's Group (Something like Harmonia, Falenas maybe?) - Circle, True Water, True Wind, True, Sun Rune, Dragon Rune, Sovereign Rune
Chaos' Group (Yuber's race, Sierra and the Vampires, Windy, another group from other world like Fog Ship Guide) - Eightfold, True Fire, Moon Rune, Night Rune, Rune of Change, Beast Rune
Balance's Group (Leknaat, Riou, people who prefers to make peace and unified all the country) - True Earth, Rune of Beginning, Soul Eater, Rune of Punishment, Gate Rune, True Lightning
The winner of the battle, None.... the power is to extraordinary for the current Suikoden World to hold, the world itself destroyed and all the True Runes destroyed... The Darkness ("Parents" of the World) extremely sad because this event, and shed another tear... then, this time hmm... Bow and Arrow reborn, and create another a new world. Not like Shield and Sword which destined to fight each other, the Bow and Arrow are destined to helps each other... XD
Oh.. there's only one person survived... VIKI!!!! She teleports to the past / future when this war of runes happened..
