Weapon: Stromkar, the Warbreaker
This greatsword was borne into combat by the barbarian warlord who first united humanity under a single banner, founding the nation of Arathor. A master tactician and strategist, King Thoradin went on to play a critical role in ending the Troll Wars. Later the sword was lost while it was being used to subdue a C'Thraxxi monstrosity in a forgotten tomb beneath Tirisfal. Abandoned and all but forgotten, Stromkar has been slowly drinking from the shadowy power there over thousands of years.
Weapon: Warswords of Valajar
In ages past, the titanic watcher Keeper Odyn betrayed the sorceress Helya, killing her and twisted her spirit into a spectral Val'kyr. He forged this pair of swords for the mightiest of his storm-forged Valarjar, but Helya stole the swords and infused them with a portion of her rage. She then gave them to her own champion, who used them to hunt the greatest of heroes and drag their souls away to serve in Helheim. These swords stir their owner into unrelenting and punishing attacks that overcome a target's defenses and leave no opening for counterattacks.
Weapon: Scale of the Earth-Warder
An impenetrable shield crafted from a scale of the black Dragon Aspect, Neltharion the Earth-Warder, before the Old Gods' corruption overcame him. The formidable vrykul king Magnar Icebreaker carried this shield into combat and won victory after victory in the face of grim odds. When he finally fell in battle, it was due to treachery by servants of the Val'kyr Helya. The shield is now entombed with King Magnar's body in the Path of Kings in Stormheim.
