A new lore book has been discovered in Patch 10.0.7! The Naga tome contains some serious hints about future story – are those Old God prophecies coming true, and is Queen Azshara making a return?
Thank you to @Queen_Ishura for discovering this!
A Song of the Depths
The Librarian of the Reach achievement, coming in 10.0.7, involves discovering several lore books being introduced with the patch. One of these books, A Song of the Depths, contains some major lore bombs to say the least.
