In the Shadow of the Sun is a short story by Sarah Pine featured on the official site. It offers a glimpse into the mind of Lor'themar Theron, regent lord of Quel'Thalas.
Originally, it was a fanfiction that won the grand prize in Blizzard's creative writing contest. It was later rereleased as official lore, with a few minor changes from the original.[1]
In the story, Aurora Skycaller and Renthar Hawkspear tell Lor'themar that Nathanos Marris died at the hands of the Scourge but never became Scourge himself, instead being called to Sylvanas' service before Arthas had a chance to sway his will. However, Nathanos himself told Horde players that he was raised as a member of the Scourge before later being freed by Sylvanas,[2] a version of events supported by Dark Mirror.
The following texts were not published as short stories but rather published on the official Blizzard websites as blog posts split into several parts. However, they are included here for completeness' sake.
