Prince Magnus encounters Nassix the Dread King for the first time in the ruins of an old castle. It is during this battle that Magnus is acquainted with the legendary "primeforge" metal crafting technique after he breaks his father's sword against Nassix's blades. Though not enchanted themselves, primeforged weapons are made by a master smith who is accompanied by a mage (usually a geomancer) who aids the smith by using their power to shape, smooth out, and thicken the ore to an almost perfectly atomic level. Obviously, such weapons are incredibly resilient and ridiculously deadly.
