The secret finding discord was hard at work trying to find the elusive Lucid Nightmare mount from the time Patch 7.3 was released until about 36 hours ago. Thanks to Wowhead and Bellular from BellularGaming on Youtube, I got my own Lucid Nightmare unicorn of my own! I spent a total of 5 hours working to get my mount, and that maze made me go bonkers for awhile, but it was totally worth it!
