Ages ago, in the darkness before time, a battle was fought between the powers of Sword and Shield. Not quite neverending, this battle ended with Shield split apart by Sword, and Sword sundered by the blow. As the pieces fell, they formed the land, and the gems upon each fell to the earth as 27 pieces of power, tiny bits of the creation of the world itself.
In time, humanity and various demihuman races - elves, dwarves, kobolds, others - flourished and formed their own civilization. Castles, ironworks, steel, boats, and eventually even gunpowder were developed, alongside the use of mystical Runes, each spawned of the 27 True Runes that fell to the world long ago. Yet periodically the power of the Runes, and the power of the 108 Stars of Destiny, would make itself known in shaking the world.
It has been only a little while since the fall of the Scarlet Moon Empire, brought about by the Liberation Army. The Republic is still rebuilding and negotiating more formal alliances, but for now, the land is at peace. For now.
