Legion Secrets

Legion is where modern secrets began: the Lucid Nightmare, the Mind-Worm and the first hidden mounts.

Legion is where secret hunting became a community sport. The Long-Forgotten Hippogryph and Kosumoth were found by players who noticed odd spawns in the Broken Isles, and from patch 7.2 Blizzard started building puzzles on purpose. The Riddler's Mind-Worm sent players across five expansions with nothing but riddles on loose pages, and the Lucid Nightmare in 7.3 added classic puzzles and a maze that pushed players to build solver tools of their own. Both of these count toward the Mind-Seeker achievement. Legion secrets are still available, and with today's character power you can finish every one of them alone.
