The Valarjar seem more or less like Titanforged in that they are automatons - Stormforged bodies housing the spirits or souls of deceased Vrykul champions. The binding seems to be done with something that is either close to or is the Light as opposed to Shadow-based Necromancy - just as Odyn's Val'kyr appear to use Light-based magic themselves as opposed to the Shadow magic of the Lich King's Val'kyr. Much of Odyn's aesthetic seems to be emphasizing the old adage: "Light is not Good." He is pro-Azeroth and works in the defense of the Titans' goals of protection and preservation, but his means are questionable or downright anti-heroic at times.
