Warborn Sorcery

The lands are divided. Set ablaze by warring factions whose battles scorch the earth, ruining it for years to come. On the eve great conflict, a child is born. One who will bring balance to a land that has degraded into chaos.
It is said that through battle one finds their true identity. For the Warborn, this statement becomes a matter of fact.
