A vein. Anduin's mind went immediately to the intricate network of veins and arteries that went through a living body. Strange how so long ago, well before anyone understood that Azeroth was a sleeping nascent titan, the term "vein" had been used to describe the ribbons of various minerals that ran throughout the world.
In the narrative, Anduin reflects on the concept of a "vein," and his thoughts connect it to the complex system of veins and arteries in living beings. This introspective moment reveals how such terminology can carry profound meanings, highlighting the interconnection between life and the foundations of the world.
Furthermore, the text draws attention to the historical usage of the term "vein" to describe mineral deposits within Azeroth. This highlights a deep-rooted relationship between the natural world and its resources, long before the existence of a greater understanding of Azeroth's nature as a nascent titan.
