We've datamined several new weapon models in the latest update to The War Within Alpha, including a very nice looking version of Shalamayne!
The sword of Anduin Wrynn, inherited from his father, was previously corrupted into Kingsmourne during the events of Shadowlands, eventually purged of that malevolent energy in the Sepulcher of the First Ones. Still in Anduin's possession, we most recently saw it in The War Within announcement cinematic, now devoid of its light and matching its wielders grizzled appearance.
