Population Migration / Travel
The Scro settle in a distant sphere, commiting both genocide and deicide against the local wood elven civilisation, the only inhabitants of the sphere.
The handful of survivors are lead by a ranger named Kuras, and disperse to other spheres. They take the name of Kuras Elves, and swear bloody vengeance upon both the goblinoids for destroying them, and the Imperial Elven Navy for refusing to defend them.
